Answer:
b) 4781 N
Explanation:
Because there is a redius do this question is talking about the acceleration force which= mv^2/r
so a=15^2/80=2.8125 m^2/s
so the force will be = m.a
F =1700×2.8125=4781.25 N

Answer:
Final velocity = 7.4m/s
Explanation:
Use the equation:
acceleration = (final velocity - initial velocity)/time
Rearrange to get:
final velocity = (acceleration * time) + initial velocity
Now just substitute with the values you already have:
Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s
Final velocity = 7.36m/s
We are using 2 sig-figs, so:
Final Velocity = 7.4m/s

suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?
We have that with v_1 =v this goes to show that the velocity of the bigger block after the collision takes place is v
From the question we are told
Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?
Generally the equation for Momentum is mathematically given as
P=mv
Therefore
[tex]m_1v_2=m_2v_2[/tex]
Hence
[tex]v_1=\frac{m_2v_2}{m_1}[/tex]
Therefore
[tex]v_1=\frac{mv_2}{2m}\\\\v_1=\frac{v_2}{2}[/tex]
Hence
[tex]2v+v=v_1+v_2\\\\v_1=v[/tex]
Now
with v_1 =v this goes to show that the velocity of the bigger block after the collision takes place is v

A 3000-kg spaceship is moving away from a space station at a constant speed of 3 m/s. The astronaut in the spaceship decides to return to the space station by switching on engines that expel fuel so that the sum of the forces exerted on the spaceship by the expelled fuel points toward the space station. What is the magnitude of the minimum force needed to bring the spaceship back to the space station
Answer:
P = m (v2 - v1) change in momentum
P = - m v1 if v2 is to be zero
F = P / t change in momentum equals applied force
F = m a = - m v1 / t
a = -v1 / t or a * t = -v1`
Any combination of a and t that is greater than v1 will bring the space station to a halt
If a is small then t must be large
Any applied force will eventually bring the ship to a halt and then begin the acceleration towards the starting point

the object. If this object is 10 kg,
how/where will it accelerate?
Answer:
the free-body diagram shows the vectors for all the forces acting on the body. The resultant vector found by summing all the individual vectors represents the net force. Since F = ma, the acceleration vector will point in the same direction as the net force, with a magnitude of F / m

If a metal has a mass of 78.2 g and a volume of 11.4 mL, what is its density?
Answer:
6.86g/mL
Explanation:
The density of the metal would be approximately 6.859 grams per milliliter (g/mL).
Given that the mass (m) is 78.2 g and the volume (V) is 11.4 mL, we can plug these values into the formula:
Density is a physical property that quantitatively expresses how much mass is contained within a given volume of a substance. In other words, it is a measure of how tightly packed the particles or molecules of a material are. Mathematically, density is defined as the mass of an object (or substance) divided by its volume. It is often denoted by the Greek letter "ρ" (rho).
Density is defined as mass per unit volume. The formula for density is:
Density (ρ) = Mass (m) / Volume (V)
Density (ρ) = 78.2 g / 11.4 mL
Now, let's calculate the density:
Density (ρ) = 6.859 g/mL
So, the density of the metal is approximately 6.859 grams per milliliter (g/mL).

What is the power generated by the car?
W = F × s
W = 15kN × 40 m
W = 15.000 N × 40 m
W = 600.000 J
P = W/t
P = 600.000 J/2 s
P = 300.000 Watt
P = 300kWatt
