A rocket of mass M = 30kg is traveling with velocity V = 1500m/s horizontally. When it explodes into two chunks of mass m1 = 20kg and m2 = 10kg. The mass observed to be moving at an angle of (theta1) 20 above the horizontal with a speed of 1000m/s just after the explosion. Find the magnitude and direction of m2. Do a calculation that allows you to determine whether this explosion was elastic or inelastic. I know how to find the magnitude and direction of m2. The problem is the second question. Im not sure how to show that the explosion is inelastic. The magnitude and direction of m2 is 2709 m/s and the direction is -14.63.
