Question

A projectile of mass M is moving through the air with speed v0 to the left when it suddenly explodes into 2 pieces. Afterwards, one piece of the projectile with mass 2/3 M is moving to the left with half its original velocity. What is the velocity of the other piece in terms of v0? A projectile of mass M is moving through the air with speed v0 to the left when it suddenly explodes into 2 pieces. Afterwards, one piece of the projectile with mass 2/3 M is moving to the left with half its original velocity. What is the velocity of the other piece in terms of v0?

Explanation / Answer

applying the conservation of momentum we get:-

Mv0 = -2M/3*v0/2+M/3*v              where v is to be found in terms of v0

=>v = 4v0
