Question

two bodies of equal masses 1 kg are collided after collision one of the body is moving with the velocity of 4 m per second if the total KE o system after collision is 12.5 J then the velocity of second body is

Answer 1

Answer is 5 m / s

12.5 = 1/2×1×v²

v² = 12.5×2

v²= 25

v = 5 m/s

Answer 2

Answer:

5 m/s

Explanation:

12.5 = 1/2 x 1 x v²

v² = 12.5 x 2

v² = 25

v = 5 m/s

I hope this will be help you.
