Question

a body of mass 100kg falls from a height of 10 m.its increase in kinetic energy is??

Answer 1

Answer:

Explanation:

when the body is released from a height of 2 meters then all the potential energy will be converted to kinetic energy.

assuming base as a reference

mgh+0=K.E.+0

so K.E.=400J

Answer 2

Answer:

I think this Q is wrong bcz we can't find kinetic energy by the given terms....this question is in the s chand book...I also hv some issues in this ....so u may found potential energy easily by the given terms by correcting the errors in the Question...
