A mass m descends a vertical distance from rest. (Neglect friction and the mass of the string.) A.) from the conservation of mechanical energy, will the linear speed of the descending mass be (1) greater than, (2) equal to, or (3) less than the square root of 2gh? Why? B.) If m=1.0 kg, M=0.30 kg, and R=0.15 m, what is the linear speed of the mass after it has descended vertical distance of 2.0 m from rest?
