    A rocket is fired vertically upward. At the instant it reaches the highest point, it explodes into three fragments having equal mass. One fragment move upward with a speed of 450 m/s following the explosion. The Second fragment has a speed of 300 m/s and is moving east right after the explosion. provide all work.

    a) What is the velocity of the third fragment after the explosion?

    b) What is the energy released from the explosion?

    Solution Preview

    We can solve this problem using conservation of momentum. All the fragments have the same mass, say, M. When the explosion happened the rocket was at its highest point, so its velocity was zero. Therefore, the total momentum before the explosion was zero (note that the rocket was flying ...
