After the initial push, the friction that the ice exerts cannot be considered negligible, and the mother comes to rest after moving a distance of 6.7 m across the ice. If their coefficients of friction are the same, how far does the son move after the push

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.
