A spring block system is kept inside a lift moving with a constant velocity `v_(0)` as shown in figure. Block is in equilibrium and at rest with respect to lift. The lift is suddenly stoped at time `t = 0`. Taking upward direction as the positive direction, write `x - t` equation of the block.

The angular frequency of a spring block system is omega_(0) . This system is suspeded from the ceilling of an elevator moving downwards with a constant speed v_(0) . The block is at reast realtive to the elevator. Lift is suddenly stopped. Assuming the downward as a positive direction, choose the wrong statement :

The block is at reast realtive to the elevator. Lift is suddenly stopped. Assuming the downward as a positive direction, choose the wrong statement :

The angular frequency of a spring block system is omega_(0) . This system is suspended from the ceiling of an elevator moving downwards with a constant speed v_(0) . The block is at rest relative to the elevator. Lift is suddenly stopped. Assuming the downward as a positive direction. Then

A spring block system is kept inside the smooth surface of a trolley as shown in figure. At t = 0 trolley is given an acceleration 'a' in the direction shown in figure. Write S - t equation of the block (a) with respect to trolley. (b) with respect to ground.

A block of mass m is placed on an inclined plane which is moving with constant velocity v in horizontal direction as shown in figure. Then find out work done by the friction in time t if the block is at rest with respect to the incline plane.

A spring block system is kept inside the smooth surface of a trolley as shown in finger. At t = 0 trolley is given an acceleration 'a' in the direction shown in figure. Write S - t equation of the block (a) with respect to trolley. (b) with respect to ground.

A block of mass M is kept in elevator (lift) which starts moving upward with constant acceleration b as shown in figure. Initially elevator at rest. The block is observed by two observers A and B for a time interval t=0 to t=T . Observer B is at rest with respect to elevator and observer A is standing on the ground. Q. The observer A finds that work done by normal reaction acting on the blocks is
