Acceleration is the rate of change of velocity. The velocity (positive means down) of a pumpkin thrown off the top of Cheadle hall t seconds after launch is 32 ft/sec (until it hits the ground). (a) What is the average rate of change of velocity between =1 and =2? 1.5 feet per second per second (b) What is the average rate of change of velocity between =1 and =1.1? feet per second per second (c) If the pumpkin lands after 2.5 seconds, what is the speed of the pumpkin when it hits? feet per second
