three cars with identical engines and tires start from rest, and accelerate at their maximum rate. car x is the most massive, and car z is the least massive. which car needs to travel the farthest before reaching a speed of 60 mi/h?
Answer: The most massive car, x, will take the longest to reach 60 mph.
Explanation: The inertia of a car is dependent on its mass. F=ma. Given that each car has the same force (identical engines) the one with the higher mass will accelerate more slowly.

2. A bowling ball is dropped off a 300 meter high bridge. A water bottle is dropped from

bowling ball has a speed of 64 m/s? *
(2 Points)
A bowling ball is dropped off a 300 meter high bridge. A water bottle is dropped from the same position 3 seconds later. the ground is the water bottle, when the bowling ball has a speed of 64 m/s is zero.
what is speed ?Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
The formula of speed is represented as s=d/t, Where, s is the speed in m.s-1, d is the distance traveled in m, t is the time taken in s
There are four types of speed such as Uniform speed, Variable speed, Average speed, Instantaneous speed
Uniform speed is an uniform speed when the object covers equal distance at equal time intervals, variable speed is defined as when the object covers a different distance at equal intervals of times.
Average speed is defined as the uniform speed the ratio of total distance travelled by an object to the total time taken by the object.
Instantaneous speed is defined as an object is moving with variable speed, then the speed at any instant of time is known as instantaneous speed.

11. A box with a mass of 1.0 kg is resting on a horizontal surface and the coefficient of friction between the block and the surface is 0.20. It is accelerated by attaching a 1.5 kg mass, as shown in the diagram. Assume that the pulley is frictionless and that the cord has negligible mass.
a. What is the acceleration of the box? What is the tension?
Answer:
We know that the force pulling the box in the positive x direction has a magnitude of m g sin 30 . Using Newtons Second Law, F = ma , we just need to solve for a :
ma=mgsin30
a=gsin30
=(10m/s2)(0.500)
=5m/s2
Answer:
A force is applied acting to the right. Assume that friction is negligible. Ikg 0.5N. For each question, one or more features of the system.

A crate of mass 50kg is pulled up a rough inclined plane, inclined at an angle of 60° to the horizontal. Determine the total work done in moving the crate to the top of the inclined 200m high.
Answer:
Wc = m*g = 50kg * 9.8N/kg = 490 N = Wt.
of crate.
Fc = 490N 60o = Force of crate.
Fp = 490*sin60 = 424.4 N. = Force
parallel to incline.
Fv = 490*cos60 = 245 N. = Force perpendicular to the incline.
Ff = u*Fv = u*245 = Force of friction.
Fap-Fp-Ff = m*a
Fap-424.4-u*245 = m*0 = 0
Fap = 424.4 + 245u. = Force applied.
L = 200m/sin60 = 231 m. = Length of
incline.
Work = Fap * L=(424.4+245u) * 231.

Find the gravitational potential energy of a body of mass 25kg,kept at a height of 4m If g=10m/s'.
Answer:
1000 JExplanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
GPE = 25 × 10 × 4 = 1000
We have the final answer as
1000 JHope this helps you
A wave moving with a speed of 0.5 m/s has a frequency of 50 Hz. What is the
wavelength of the wave?
A. 0.10 m
B. 0.01 m
C. 100 m
D, 25 m
Answer:
0.01 mExplanation:
The wavelength of the wave given it's velocity and frequency can be found by using the formula
[tex] \lambda = \frac{c}{f} \\[/tex]
where
c is the speed of the wave
f is the frequency
From the question we have
[tex] \lambda = \frac{0.5}{50} = 0.01 \\ [/tex]
We have the final answer as
0.01 mHope this helps you

Composition varies in the asteroid belt. Inner-belt asteroids tend to be rich in ____. Outer-belt asteroids tend to be rich in ____.
Inner-belt asteroids tend to be rich in SILICATE, whereas outer-belt asteroids tend to be rich in CARBON. An asteroid is a rocky object (much smaller than a planet), which orbits around the Sun.
The asteroids are composed of different elements (e.g., carbon, nitrogen, hydrogen, oxygen, silicate, etc).
The asteroid belt is a region in the Solar System, located between the orbits of Mars and Jupiter.
The size of the asteroids localized in the asteroid belt range from a few meters to almost 1000 kilometers (km) wide.
Approximately half mass of the asteroid belt is composed of only four asteroids (i.e., Ceres, Vesta, Pallas, and Hygiea).

the graph below shows the densitys of rock
Explanation:
The terms heavy and light are commonly used in two different ways. We refer to weight when we say that an adult is heavier than a child. On the other hand, something else is alluded to when we say that rock is heavier than soil. A small rock would obviously weigh less than a roomful of soil, but rock is heavier in the sense that a rock of given size weighs more than the same-size sample of soil. What we are actually comparing is the mass per unit volume, that is, the density. In order to determine these densities, we might weigh a cubic centimeter of each sample. If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm–3 and that of the soil as 1.20 g cm–3. Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below). (Note that the negative exponent in the units cubic centimeters indicates a reciprocal. Thus 1 cm–3 = 1/cm3 and the units for our densities could be written as g/cm3, or g cm–3. In each case the units are read as grams per cubic centimeter, the per indicating division.) We often abbreviate "cm3" as "cc", and 1 cm3 = 1 mL exactly, by definition.

With what speed does the stone strike the
water?
Answer in units of m/s.
Hi there!
We can begin by finding the final VERTICAL velocity of the ball.
Use the following kinematic equation: vf² = vi² + 2ad
The ball does not have any initial velocity in the vertical direction so:
vf² = 2ad
Plug in given values:
vf² = 2(9.81)(44) = 29.38 m/s
Find the TOTAL speed using the pythagorean theorem (involving both the horizontal velocity which remains the same and vertical velocity)
v = √(21²) + (29.38²) = 36.115 m/s
