Position versus time
graph of position versus time with position on y axis from 0 to 120 miles and time on x axis from 0 to 5 hours. segment 1 goes from 0, 0 to 1, 20. segment 2 goes from 1, 20 to 2, 40. segment 3 goes from 2, 40 to 3, 70. segment 4 goes from 3, 70 to 5, 85.

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.

Energy transformations that involve one transformation from one type of energy to another are called transformations.
