A man of weight mg is moving upwards in a rocket with acceleration 4g. His apparent weight in side the rocket will be?
If a body of mass m is carried by a lift moving with an upward acceleration a,then the forces acting on a body are (i) the reaction R on the floor of a lift upwards (ii) the weight mg of the body acting vertically downwards . The equation of motion will be given by
A)R=mg-ma
B)R=mg+ma
C)R=ma-mg
D)R=mg*ma
A man of mass M stands on a weighing machine in an elevator accelerating upwards with an acceleration a0 . Calculate the reading of the weighing machine
