A steel ball is dropped from a building's roof and passes a window, taking 0.12 s to fall from the top to the bottom of the window, a distance of 1.20 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.12 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 1.74 s. How tall is the building?

Answer: 10.12 A key is dropped from a bridge that is 40.0 m bove the water. At the moment the key is released a model boat is 10.5 m away from the bridge and moving towards the bridge with constant velocity. If the key falls directly into the model boat, calculate the Velocity of the boat. Answer: 11. [2pt] Arie is aimed honuntaily a target located 345 m away.
