A body of mass 5 kg is acted upon by two perpendicular forces 8 N and 6 N. Give the magnitude and direction of the acceleration of the body.

A body is acted upon by a number of external forces. Can it remain at rest.

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

A body of mass 6 kg is acted upon by a force which causes a displacement in it given by x = t^2/4 meter, where t is the time in second. The work done by the force in 2 seconds is

Define centripetal force.A particle of mass m is rotating around a circular path of radius r. Find the centripetal acceleration of the particle and the magnitude and direction of the centripetal force acting on it.

A body of mass 4kg is moving with a momentum of 8 kg *m*s^(-1) . A force of 0.4 N acts on it in the direction of motion of the body for 10 seconds. Determine the increases in kinetic energy in joules.

A body of mass 3 kg acted upon by a constant force is displaced by 's' meter, given by the relation s=(1)/(3)t^(2) , where t is in second. Work done by the force in 2 seconds is

A body of mass 10 kg is raised to a height of 10 m with an upward force of 196 N . Find the work done by the upward force and the work done against gravitation. Show that the total energy in this case is equal ot the work done by the upward force . [g=9.8 m*s^(-2) ]
