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...

A tennis ball is a hollow sphere with a thin wall It is set rolling without slipping at 4.12 m/s on a horizontal section of a track as shown in the figure below. It rolls around the inside of a vertical circular loop of radius r = 46.7 cm. As the ball nears the bottom o the oop, the shape o the track deviates rom a perfect circe so that the bal eaves the track at a point 80 cm...
