A body of mass 2 kg is thrown up at a velocity of 10 ms. Find the kinetic energy of the body of the time of throw. Also find the potential energy of the body at highest point.

A body starts from rest moves with constant acceleration p. Find the ratio of the distances travelled by the body in 5 seconds and 5th second.

The displacement x of a body of mass 10 kg moving in one dimension under the action of a constant force is related to time by the equation t = sqrtx + 3 . Find the work done by the force in first 5 seconds.

A body of mass 10 kg is acted upon by two perpendicular forces 6N and 8N. Find the magnitude of acceleration produced in the body.

A string is wrapped around the rim of a wheel of moment of inertia 0.20 kg m^2 and radius 20 cm.the wheel is free to rotate about its axis .Initially,the wheel is at rest.The string is now pulled by a force of 20 N.Find the angular velocity of the wheel after 5.0 seconds.

A force of 100 N acts on a body at an anle 30^@ with the horizontal.If the body moves a distance 20 m in 5 seconds in the horizontal direction,calculate the power being suppied by the source of 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?
