A man weighs 80 kg. He stands on a weighing scale in the lift, which is moving upward with a uniform acceleration of 5 ms^-2 what whould be the reading on the scale? (g = 10 m//s^2) .

A block of mass 25 kg is raised by a 50 kg man in two different ways as shown in Fig. 5.19. What is the action on the floor by the man in the two cases ? If the floor yields to a normal force of 700 N, which mode should the man adopt to lift the block without the floor yielding ?

A person normally weighing 50 kg stands on a massless platform which oscillates up and down harmonically at a frequency of 2.0 s^-1 and an amplitude 5.0 cm. A wighing machine on the platform give s the persons weight against time If answer to part is yes, what will be the maximum and minimum reading in the machine and at which position?
