Question

A 10 kg bomb explodes into two parts. A 6 kg piece flies off with a speed of 6 m/s to the right. Find the speed and direction of the other piece if: 1 Phys 1201 Fall ’19 HW 5 Due Friday 10/25/19 by 5pm a) The bomb is stationary when it explodes. b) The bomb is moving to the right with a speed of 5 m/s when it explodes.

Answer 1

This question is based on concept of

1. Conservation of momentum

2. Knowledge of direction

3. Mathematical simplification

The detailed solution is described below

M = 10 kg V = + 6 m/s (t for right direction) @ Foom Conservation of momentum, We have LU = 0 m/s (bomb is stationary at e Stationary at explosion MU laxa 0 ou ₂ CM₂ = m, v tm, V2 = 6*6+4* V = 36 + 4V = -9 m/s Anowe & its 2 » Thus, Speed direction is of to other piece is 9 m/s the left. Answer 6 2 - 3 - Now MU 10*5 50 ₂ again from Conservation of momentum - mi v tm V₂ = 6*6 + 482 = 36 +42 - 14/4 = + 3.5 m/s Anowe Speed of direction other piece is 3.5 m/s & is to the right Answer) THANKS!!!

THANK you very much
