Raymond · Answer 1

While lifting two object the machine needs the different momentum for different mass object.

Explanation:

Momentum is the quantity of motion contained in an object. Usually it is measured by the product of mass and velocity. Momentum of first mass = 2 kg * 2 m/sec = 4 kg m/sec Momentum of second mass = 4 kg * 3 m/sec = 12 kg m/sec So the machine requires higher mass in motion for second object (i. e. momentum) than the first one while lifting.
