Question

A body of mass 0.16kg, is about to be rolled down a ramp which has a height of
3m. Calculate the velocity of the body at point A which is at 0.5 m above the ground.

And also the ball's final velocity at B when it hits the ground as shown in the figure.
Take g=10 m s2
A object of mass 50.0 kg moves with a velocity of 11.2 m/s and an event occurs
whereby it transfers 1,539 J of energy to another object as work. What is the new
velocity of the object after the event?​
