4. A bullet fired into a block of wood to determine the speed of the bullet. The block is attached by a rod to a low friction axle. The bullet becomes embedded in the wood and the maximum angle the rod rotates is measured. a. Use the numbers in the diagram to determine the speed of the bullet before it hit the block of wood. Hint: use the angle to determine the speed of the block and bullet just after the bullet becomes embedded in the wood. 30° 0.8 m D> 0.8 kg 4 gram: b. How much mechanical energy was lost during the collision? Comment: You should find that most of the mechanical energy was lost. =====:::

Jill threw a dodgeball completely horizontal in x-direction with velocity of +5 m/s and mass of .5 kg. At the same time her friend threw a dodgeball with the same mass in the -x direction and a velocity of -2 m/s. The balls hit each other, and Jill's ball was deflected 30° above the original path, while her friend's deflected 20⁰. below the initial path. a. Ignoring gravity, solve the velocity of each ball after the collision, using a free body diagram. b. If both balls had a magnitude of 3 m/s, how much kinetic energy was "lost" during the collision?
