Calculate the increase in potential energy as a block of 2kg is lifted up through 2m.
Asked by rajneesh kumar | 5th Dec, 2013, 08:40: PM
M = 2 kg
height h = 2 m
When the block is at ground, its initial potential energy is zero.
When the block is lifted upto 2 m height potential energy increases.
Increase in P.E = mgh
= 2 x 2 x 9.8
= 39.2 J
