Answer 1

Explanation:

your answer

A body of mass 3 kg is moving with a velocity of 4 ms1

towards the right, collides head-on with a body of mass 4 kg

moving in the opposite direction with a velocity of 3 ms

After collision the two bodies stick together and move with a

common velocity, which is

Thus, 12 + 3 = 15, 12/3 = 4;

22 + 11 = 33, 22/11 = 2;

18 + 9 = 27, 18/9 = 2.

So, 32 + X = 36 and 32/X = 8

or, X = 4.

Hence, option (B) is the correct answer.
