B. Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.
We have that the instantaneous velocity of the shuttlecock when it hits the ground is
[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]
From the question we are told
Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.
Generally the equation for acceleration is mathematically given as
[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]
Where
acceleration is still -9.81 m/s2,
Hence,
[tex]V^2-U^2=2(-9.81)*-H[/tex]
Therefore
[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

what force is needed to make a ball fall on earth if it had a mass of 13kg
I'd appreciate if someone could help me thank you
Newton's second law allows finding the answer for the force that attracts the body is 127.4N
Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.
F = m a
Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.
When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship
W = m g
Where W is the force called weight, m the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration (g = 9.8 m / s²)
They indicate that the mass of the body is m = 13 kg, let's calculate the weight
W = 13 9.8
W = 127.4 N
In conclusion using Newton's second law we can find the answer for the force that attracts the body is 127.4N

will an object have the same weight on moon as it does ?
Answer:
The mass of an object is the same everywhere either on earth or moon.
The weight of an object depends on a gravitational acceleration and it's different from one on earth and that on moon.
therefore the weight changes but the mass is the same.

how much is the velocity of a body when it travels 600m in 5 minutes ?
its answer is 2M/S
but I don't know solution to take this answer
Explanation:
Displacement= 600 m
Time= 5×60 = 300 sec
Velocity= Displacement/time
= 600/300
= 2 m/s

What is the force of a object that has a mass of 7 kg and an acceleration of 6 m/s/s
Answer:
42 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
mass = 7 kg
acceleration = 6 m/s²
We have
force = 7 × 6 = 42
We have the final answer as
42 NHope this helps you

3. Pandemic took its toll on our health. We cannot go outside to do our physical activities and socialize with other people like we used to. To maintain our active lifestyle even in the comforts of our home, we must do balanced activities. This will help us take good care of ourselves and help us cope with what is happening around us. We can identify the tasks we do at home as work, or no work done.

A. the force that the chair exerts on the desk after it is pushed in
B. the force of friction acting on the chair
C. the force of gravity acting on the chair
D. the force from the chair on the student
Answer:
Ans : C
Explanation:
C. The force of gravity acting on the chair
Answer:
D. the force from the chair on the student
Explanation:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

glacier known to mankind. It travels 8.2 millimeters every day. How far does the glacier move in a YEAR?
Convert units and show your work. (HINT-> how many days are there in a year? How many millimeters
in a meter?)
Answer:
8.2 mm / day * 1 m / 1000 mm = .00082 m / day distance in 1 day
365 day / 1 yr * .00082 m / day = .30 m / yr
