A hot air balloon is rising vertically with a velocity of 10.0 feet per second. A very small ball is released from the hot air balloon at the instant when it is 960 feet above the ground. Use a(t)=−32 ft/sec2 as the acceleration due to gravity.
1. How many seconds after its release will the ball strike the ground? Round the answer to the nearest two decimal places.
2. At what velocity will it hit the ground?
