Question

Young Jeffrey is bored, and decides to throw some things out of the window for fun. But since he is also very curious, he decides to do so in a controlled way. Jeffrey takes a rock, his tennis ball, and one of his father's golf balls and sets them on the sill of an open window. Then, he uses a flat board to carefully push them all out of the window at the same time. The second-story window is 14.0 ft above the ground, and all three objects hit the ground just 0.650 ft away from the base of the house at the same time, 0.933 s after they were dropped. The rock hits with a thud and stays put, but the other two objects bounce. After another 0.699 s, the tennis ball reaches a maximum height of 7.88 ft, while the golf ball is 11.0 ft off the ground and still rising. Both have travelled an additional 0.488 ft horizontally Calculate the magnitude of the average velocity ū of each object during these 1.63 s. Urock fu/s ft/s Dennis fus
