A constant force acts for 3s on a body of mass 16 kg and then ceases to act. During the next 3s, the body covers 81m. Find the magnitude of the force.

A constant force of 15 N acts on a body of mass 5 kg. Find the acceleration produced.

A constant force acts on object of mass 5 kg for a duration of 2s It increases the object's velocity from 3m/s to 7m/s Find the magnitude of the applied force. Now if the force were applied for a duration of 5s what would be the final velocity of object?

The buoyant force on a body acts in

Oif a force 20 N is applied on a body of mass 5 kg at rest then find the kinetic energy of the body after 10s.

A constant force acting on a body of mass 3.0 kg changes its speed from 2.0 m s^-1 to 3.5 m s^-1 in 25 s. The direction of the motion of the body remains unchanged. What is the magnitude and direction of the force ?

A constant force of 5N is applied continuously on a body of mass 10kg for 4 seconds. The body moves 800cm along a straight line. What is the velocity of the body when the force was applied initially?
