An object of mass `2`kg, moving in a straight line, is accelerated from `2m/s` to `6m/s` by a force of `5N` acting along the same direction. Then work done will be...

A 5kg mass is accelerated from rest to 60 m/s in 1 sec. what force acts on it:

A ball of mass 150 g moving with an acceleration 20 m//s^(2) is hit by a force, which acts on it for 0.1 s. The impulsive force is

A particle of mass 2 kg starts moving in a straight line with an initial velocity of 2 m//s at a constant acceleration of 2 m//s^(2) . Then rate of change of kinetic energy.

An object of mass 1kg travelling in a straight line with a velocity of 10m//s collides with, and sticks to, a stationary wooden block of mass 5kg . Then, they both move off together in the same straight line. Calculate the total momentum just before the impact and just after the impact. Also, calculate the velocity of the combined object.

A body of mass 5 kg is moving with a velocity of 20 m/s. If a force of 100 N is applied on it for 10 s in the same direction as its velocity, what will be the velociy of the body ?

The velocity-time graph of a particle moving in a straight line is shown in figure. The mass of the particle is 2kg . Work done by all the forces acting on the particle in time interval between t=0 to t=10s is

On an object of mass 1 kg moving along x-axis with constant speed 8 m/s, a constant force 2 N is applied in positive y-direction. Find its speed after 4 seconds.

If the velocity v of a particle moving along a straight line decreases linearly with its displacement from 20 m//s to a value approaching zero at s = 30 m, determine the acceleration of the particle when s = 15 m.

A lift of mass 200 kg is moving upward with an acceleration of 3m//s^(2) . If g=10 m//s^(2) then the tension of string of the lift will be :
