Question

AB is a string whose one end A is fixed at the highest point of a ring placed in vertical plane. C is the centre of the ring. At other end B of the string, is attached a bead of mass m, which can slide along the ring. If the bead is in equilibrium at B & string is taut then the tension in the string is

A block of mass m sliding down an incline at constant speed is initially at a height h above the ground, as shown in the figure above. The coefficient of kinetic friction between the mass and the incline is m. If the mass continues to slide down the incline at a constant speed, how much energy is dissipated by friction by the time the mass reaches the bottom of the incline?
