Acertain car's drive-train produces a force of 5300 n as it accelerates from 0
to 60 mph in 10.0 seconds. if this acceleration covers a distance of 125 m.
determine the power output of the car's engine.

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.
