A particle of mass m is projected with velocity v at an angle with the horizontal. At its highest point, it explodes into two pieces of equal mass, one of the piece continue to move on the original trajectory, then the velocity of second piece is
Options
- A2 v
- Bv
- C3 v
- Dv 2
Correct answer
B. v
Step-by-step solution
According to the law of conservation of linear momentum at the highest point, m v = m 2 (v )+ m 2 v^ m v - m 2 v = m 2 v^ v^ =2 (v - v 2 )=v
