A car jumps off a ramp with a Kinetic energy of 5,000 joules. This same car has a gravitational potential energy of 4,685 joules at some point when it is falling to the ground, after jumping off the ramp. When the car lands on the ground, the springs of this car’s suspension compress and then come back to normal exerting an elastic potential energy of 4,968 joules. What is the car’s total mechanical energy (TME)?

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.
