The velocity of a body changes from `2m//s` to `4 m//s`. When a constant force is acting on it. Mass of the body is 1 kg. Calculate the work done by the force.

The velocity of a body of mass 5 kg changes from 20 m/s to 10 /s. calculate the change of momentum of the body.

The velocity of a 10 kg mass is increased from 2m *s^(-1) to 4m*s^(-1) . The amount of work done in doing so is

A body of mass 100 g is at rest. A force acts on it for 3 seconds and the body attains a velocity of 15 cm/s. calculate the magnitude of force.

A body of mass 10 kg is raised by 5m . What is the work done ?

What force will change the Velocity of a body of mass 1 kg from 20 m// s to 30 m//s in 2 seconds?

A force is acting on a body in motion, but is not doing any work. Give an example of such a force.

A body is constrained to move along the z-axis is subject to a constant force F = (-hati+2hatj+3hatk) N . Calculate the work done by this force in moving the body a distance of 4m along the z-axis .

A body of mass m , starting from rest , moves with constant acceleration . After a time T it attains a velocity V. Show that the work done by the body in time t=1/2 m (V^2)/(T^2)*t^2*

What force will change the velocity of body of mass 1 kg from 20 m/s to 30 m/s is 2 s?
