Question

suppose a hammer of mass 1kg falls freely on a wooden block if it falls from a height of 1m, how much kinetic energy will it have just before hotting the wooden block.​

Answer 1

Explanation:

At height of 1m hammer has potential energy which will be converted into kinetic energy.

Before hitting the wooden block all potential will be converted to kinetic because energy is conserved.

K.E=mgh

=1×10×1

=10J
