A block of mass 'm' is placed on the floor of a lift, moving upward with an uniform acceleration a = g. ( mu is the coefficient of friction between block and the floor of lift). If a horizontal force of umg acts on the block, then horizontal acceleration of the body is .......

A block with a mass of 2 kg hangs without vibrating at the end of a spring of spring constant 500N//m , which is attached to the ceiling of an elevator. The elevator is moving upwards with an acceleration (g)/(3) . At time t = 0 , the acceleration suddenly ceases. (a) What is the angular frequency of oscillation of the block after the acceleration ceases ? (b) By what amount is the spring stretched during the time when the elevator is accelerating ? (c )What is the amplitude of oscillation and initial phase angle observed by a rider in the elevator in the equation, x = Asin (omega t + phi) ? Take the upward direction to be positive. Take g = 10.0 m//s^(2) .

A spring of force constant 200Nm^(-1) has a block of mass 10 kg hanging at its one end and the other end of the spring is attached to the celling of an elevator. The elevator is rising upwards with an acceleration of g/4 and the block is in equilibrium with respect to the elevator . when the acceleration of the elevator suddenly ceases , the block starts oscillating . What is the amplitude (in m) of these oscillations ?
