A block of mass 5 kg is dropped from top of a building. Then the mamiitude of force applied by the block on the earth whne falling is :

A stone is dropped from the top of a building in a high wind. The wind exerts a steady horizontal force on the stone as it falls. The path of the string is

A block of mass 4kg is released from the top of a rough inclines plane of height 10 m . If velocity of the block is 10 m//s at the bottom of the inclined then work done by the friction force on the block will be

A block of mass 2 kg rests on a horizontal surface. If a horizontal force of 5 N is applied on the block, the frictional force on it is ("take", u_(k)=0.4, mu_(s)=0.5)

A block of mass 2 kg rests on a horizontal surface. If a horizontal force of 5 N is applied on the block, the frictional force on it is ("take", u_(k)=0.4, mu_(s)=0.5)

A block of mass 2 kg is placed on the floor. The coefficient of friction is 0.4. If a force of 2.5 is applied on the block horizontally, what will be the state of block. Give reason.

A block of mass 5 kg is pulled along a horizontal. The friction coefficient between the block and the surface is 0.5 . If the block travels at constant velocity, find the work done by this applied force during a displacement 4 m of the block.

A block of unknown mass is at rest on a rough, horizontal surface. A horizontal force F is applied to the block. The graph in the figure shows the acceleration of the block with respect to the applied force. The mass of the block is
