Suppose one bullet with M=5.12g moving to the right with a speed of 250 m/s directed at 21.3 degrees above the horizontal collides and fuses with another bullet of mass m=3.05g moving to the left at speed v=282 m/s directed at 15.4 degrees above the horizontal.
a. What is the magnitude of their common velocity immediately after the collision?
b. What is the direction of their common velocity immediately after the collision? Measure this angle in degrees from the horizontal
c. What fraction of the original kinetic energy was lost in the collision?
