A mass m descends a vertical distance from rest.(Neglectfriction and the mass of the string.) A.) from theconservation ofmechanical energy, will the linear speed of thedescending mass be(1) greater than, (2) equal to, or (3) less thanthe square root of2gh? Why? B.) If m=1.0 kg, M=0.30 kg, and R=0.15 m, what is thelinear speed of the mass after it has descendeda vertical distanceof 2.0 m from rest?
