A particle of mass m moves from rest under the action of a constant force F which acts for two seconds. The maximum power delivered is

A particle of mass m moves from rest under the action of a constant force F which acts for two seconds. The maximum power attained is

A block of mass m is taken from A to B under the action of a constant force F. Work done by this force is

A particle of mass M is initially at rest starts moving under the action of a constant force Fhati . It encounters the resistance of a stream of fine dust movingwith velocity -v_(0)hati , which deposits matter on it at a constant rate rho , show that its mass will be m when it has travelled a distance-

An object of mass m, initially at rest under the action of a constant force F attains a velocity v in time t. Then, the average power supplied to mass is

Under the action of a constant force, A particle is experiencing a constant acceleration. The power is

A particle of mass m moves from A to C under the action of force vecF = 2xyhati + y^2 hatj , along different paths as shown in figure.

The kinetic energy acquired by a mass m staring from rest under the action of a force F = kt is :

A car of mass M is accelerating on a level smooth road under the action of a single force F acting along the direction of motion. The power delivered to the car is constant and equal to p. If the velocity of the car at an instant is v, then after travelling a distance of (7 Mv^3)/(3p) the velocity become kv where k is__________.
