Question

You stand on a top of a lighthouse while your friend is on the ground outside. You peered into the window and dropped the bulb used on the lighthouse and asked your friend to check if it is still okay. He caught the bulb with ease after 4. 29 seconds then tossed it back up to you and it lands directly into your hands. What is the velocity of the bulb at the exact moment your friend tossed it back up to you? Need this within 3 hours help

Answer 1

fell for 4.29 s
v = g t = 9.81 * 4.29 = 42.1 meters/second down
needs that same peed up to reach top
