Radius at the Earth is 64× 10^3 km, height at the Mount Everest is 8848 km. If the value of acceleration due to gravity of the Earth is 9.8 m/s calculate the velue of acceleration due to greviay at the top .also find the weight of the body of mass 25 kg on the top of the Mount Everest,
​

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.
