a block is kept on the floor of an elevator at rest. The elevator starts descending with an acceleration of 12 m/s^2 . Find the displacement of the block during the first 0.2 s after the start. Take g=10 m/s^2 .

A block is kept on the floor of an elevator. The elevator starts descending with an acceleration of 12 m//s^(2) the displacement of the block during 1^(st) one second wth respect to elevator is-

A block of mass m is kept on a platform Platform starts moving upwards with an acceleration of g/2 . Find the work done by the normal force on the block in the first one second.

A block of mass 2 kg rests on the floor of an elevator , which is moving down with an acceleration 'g' , then the apparent weight of the block is [ take g = 10 m//s^(2) ]

A block is placed over a plank. The coefficient of friction between the block and the plank is mu= 0.2. Initially both are at rest, suddenly the plank starts moving with acceleration a_(0) = 4m//s^(2). The displacement of the block in 1 is (g=10m//s^(2))

The elevator shown in figure is descending with an acceleration of 2m/s^2 . The mass of the block A is 0.5 kg. What force is exerted by the block A on the block B?

The elevator shown in fig. is descending with an acceleration of 2 m//s^(2) . The mass of block A is 0.5 kg. The force exerted by the block A on the block B is

The elevator shown in fig. is descending with an acceleration of 2ms^(-2) . The mass of the block A=0.5kg . Find the force (in Newton) exerted by block A on block B.
