What is the work done by the gravity when an object of mass m is taken from ground to some height h with constant velocity ?

A block of mass m is moving down with constant velocity along an inclined plane of inclination theta . What is the work done by external force in pulling the block along the inclined plane through a height h with constant velocity?

A block of mass m is moving down with constant velocity along an inclined plane of inclination theta . What is the work done by external force in pulling the block along the inclined plane through a height h with constant velocity?

A body dropped from a height h with initial velocity zero, strikes the ground with a velocity 3 m/s. Another body of same mass is thrown from the same height h with an initial velocity of 4 m/s. Find the final velocity of second mass, with which it strikes the ground.

An object of mass m is projected from the ground with initial speed v_(0) Find the speed at height h.

A body dropped from a height h with initial velocity zero, strikes the ground with a velocity 3 m/s. Another body of same mass dropped from the same height h with an initial velocity of 4m/s. Find the final velocity of second mass with which it strikes the ground.

What is the work done by gravitational force in taking a mass m to a height h with uniform motion?

How much work is done when a body of mass m is raised to a height h above the ground?
