Three equal mass lumps of clay flying through the air hit each other, stick, and fly off together. The originalvelocity of one lump was 4 m/s in a direction 450 south of east.Another was 3 m/s in the west direction and the last was 2 m/s inthe north direction. (a) What will the final velocity of the stuck-together lumps after the collision? (b) If the mass ofeach individual lump was 50 g what was the loss of kinetic energyduring the collision?
