Chapter 2, Problem 61P
GO A steel ball is dropped from a building’s roof and passes a window, taking 0.125 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 0.125 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is2.00 s. How tall is the building?

A steel ball is dropped from a building's roof and passes a window, taking 0.117 s to fall from the top to the bottom of the window, a distance of 1.22 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.117 s. Assume that the upward flight is an exact reverse of the fall. The time spent below the bottom of the window is 1.90 s. How tall is the building?------m
A ball is thrown straight up from ground level. It passes a 2-m-high window. The bottom of the window is 7.5 m off the ground. The time that elapses from when the ball passes the bottom of the window on the way up, to when it passes the top of the window on the way back down is 1.3 s
What is the initial speed?
