Consider an elastic collision (ignoring friction and rotationalmotion). A queue ball initially moving at 2.9 m/s strikes a stationary eight ball of the same size and mass. After the collision, the queue ball’s final speed is 1 m/s. Find the queue ball’s angle with respect to its original line of motion.
A tuning fork with a frequency of 320.0Hz and a tuning fork ofunknown frequency produce beats with a frequency of 4.5Hz. What is the frequency of the other tuning fork
Consider the same situation, but now let the initial speed v_0 of first ball be given and treat the height h of the building as an unknown. What should the height of the building be for both balls to reach the ground at the equivalent time for v_0..
