In an intense battle, gunfire can be so concentrated that bullets from opposite sides collide in midair. Suppose that a bullet (with mass M = 5.12 g moving to the right at a speed V = 219 m/s directed 21.3° above the horizontal) collides and fuses with another with mass m = 3.05 g moving to the left at a speed = 282 m/s directed 15.4° above the horizontal. (a) What is the magnitude of their common velocity immediately after the collision? W m/s (± 0.2 m/s) (b) What is the direction of their common velocity immediately after the collision? (Measure this angle from the horizontal.) degrees (+0.2 degrees) (c) What fraction of the original kinetic energy was lost in the collision? (± 0.002)
