A 2 cm cubical lock of mass 2 kg is lying on the ground What is the pressure exerted by the block on the ground?

A block of mass 15 kg is placed on a long trolley. The coefficient of friction between the block and the trolley is 0.18. The trolley accelerate from rest with 0.5 ms^-2 for 20 s and then moves with unifrom velocity. Discuss the motion of the block as viewd by an observer with the trolley.

A block of mass 15 kg is placed on a long trolley. The coeffcient os static friction between the block and the trolley is 0.18. The trolley accelerates from rest with 0.5 m s^-2 for 20 s and then moves with uniform velocity. Discuss the motion of the block as viewed by:- an observer moving with the trolley.

A block of mass 15 kg is placed on a long trolley. The coeffcient os static friction between the block and the trolley is 0.18. The trolley accelerates from rest with 0.5 m s^-2 for 20 s and then moves with uniform velocity. Discuss the motion of the block as viewed by:- a stationary observer on the ground.

A body of mass 6 kg is kept at a height of 5 m from the surface of earth. Find the potential energy of the body.

A coper block of mass 2.5 kg is heated in a furnace to a temperature of 500 ^@C and then placed on a large ice block. What is the maximum amount of ice that can melt? (specific heat of copper = 0.39 J g^-1 C^-1 , heat of fusion of watter = 335 J g^-1 ).

A table-top measures 2 m 25 cm by 1 m 50 cm.What is the perimeter of the to of the table?

A bullet of mass 0.012 kg and horizontal speed 70 m s^-1 strikes a block of wood of mass 0.4 kg and instantly comes to rest with respect to the block. The block is suspended from the ceiling by means of thin wires. Calculate the height to which the block rises. Also, estimate the amount of heat produced in the block.
