In midair an M = 135 kg bomb explodes into two pieces of m1 = 105 kg and another, respectively. Before the explosion, the bomb was moving at 20.0 m/s to the east. After the explosion, the velocity of the m1 = 105 kg piece is 62.0 m/s to the east. Find the velocity (in m/s) (with a proper sign) of the other piece after the explosion.

-117 m/s

Explanation:

We are given that

Mass, M=135 kg

Let m be the mass of another piece

Mass of another piece=135-105=30 kg

V=20 m/s

We have to find the velocity of the other piece.

According to law of conservation of momentum

Substitute the values

Hence, the velocity of other piece after the explosion=-117 m/s

good looking response

b would be the answer
