Question

A basketball is rolling down a hill. When you start watching it, it has a total energy of -11 Joules.
When it reaches the bottom of the hill, it has a vertical position of -6 meters. If the basketball
weighs 0.6 kg, what is the kinetic energy in units of Joules of the basketball when it reaches the
bottom of the hill? Assume the system is closed and the effects of friction are negligible. Recall that
g = 10m

A child starts at rest and slides down a frictionless slide as in picture. The bottom of the track is a height h above the ground. The child then leaves the track horizontally, stiking the ground at a distance d as shown. a) Using conservation of energy, find the speed the child at the end of the slide b) Using your answer to part(a) and the equation related to a projectile, determine the initial height H of the child above the ground in terms of h and d
