Question

what happens to kinetic energy of a body if velocity of the body is halved.its mass is doubled​

Answer 1

Answer:

If the velocity of a body is halved, its kinetic energy becomes one fourth as kinetic energy is directly proportional to velocity squared

Explanation:

hope it helps

pls mark me as branliest

Answer 2

Answer:

New kinetic energy becomes, So, the new kinetic energy of the object gets doubled.

Explanation:

Let KE=

=2KE

∴ KE is doubled.
