Question

1.A ball is initially rolling along the ground with a linear speed of 4.75 meters per second (m/s). It then rolls up a hill. After the ball gets to the top of the hill, its linear speed is reduced to 2.05 m/s. The ball is a hollow sphere, with a moment of inertia given by
I = 2MR2 /3. Assume the total mechanical energy of the ball is conserved, and it rolls without slipping the whole time. What is the height of the hill, in meters?

Problem 2
A ball is initially rolling along the ground with a linear speed of 4.75 meters per second
(m/s). It then rolls up a hill. After the ball gets to the top of the hill, its linear speed is
reduced to 2.05 m/s. The ball is a hollow sphere, with a moment of inertia given by
