यदि किसी गतिमान वस्तु का रेखीय संवेग दो गुना हो जाता है, तो उसकी गतिज ऊर्जा किस गुणांक से बदल जाएगी?

A load of 17.5 kg is lifted through a height of 5 metres. Find the work done in joules (taking g = 10 m/s2).

The power of a crane which lifts a mass of 1000 kg to a height of 20 m in 10 s is: (g = 9.8 m/s2)

If the kinetic energy of a moving object is increased by 300%, by what percentage does its linear momentum increase?
