Asteel 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 1.76 s. how tall is the building?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
