Answer:
c
Explanation:
When a satellite is orbiting the earth , a constant force is being applied on it which means it must has acceleration. Also the direction of satellite is always being changed when it is orbitting to there is always change in the velocity vector which means acceleration.
You can view in the attached diagram to understand how the velocity is being changed.

Answer:
The velocity at the bottom is
Explanation:
From the question we are told that
The total distance traveled is
The mass of the block is
The height of the block from the ground is h = 0.60 m
According the law of energy
Where PE is the potential energy which is mathematically represented as
substituting values
So
KE is the kinetic energy at the bottom which is mathematically represented as
So
substituting values
=>
=>
=>
