A man exerts a force of 200 N in pulling a cart at a constant speed of 16ms^-1 then the power spent by man is 

A body at rest is acted upon by a force F such that it acquires a speed while moving with an acceleration a. The work done by the force on the body is

 A body of mass 40 kg runs up a flight of 50 steps, each 10 cm high in 14 seconds them work done by the boy is

A man exerts a force of 200N in pulling a cart at a constant speed of 16ms^-1.  Then the power spent by man is

A boy weighing 350 N runs up a flight of 30 steps, each 20 cm high in 1 minute.   Then the work done is

A particle of mass 2kg was initially at rest,if a force of 10 N is applied for 10 seconds, the kinetic energy of the particle is

The expression for power is given by

 A body at height possesses:
