1.) The water slide shown below ends at a height of 1.50 m above the pool. If the person starts from rest at point A and lands in the water at point B, which has a horizontal distance L = 2.52 m from the base of the slide, what is the height h of the water slide? (Assume the water slide is frictionless.)
2.) An object moves along the x axis, subject to the potential energy shown below. The object has a mass of 1.5 kg, and starts at rest at point A.
What is the object's speeds at point B, at point C, and at point D?
It provides two applications of conservation of energy to find the height of water slide and the speeds of the object, respectively.
