A basketball has a coefficient of restitution of 0.843 0.843 in collisions with the wood floor of a basketball court. The ball is dropped on such a floor from a height of 2.91 m 2.91 m . How high is its fourth bounce?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
