. A potato is launched vertically upward with an initial velocity of 100 ft/s from a potato gun at the top of an 85-foot-tall building. The distance in feet that the potato travels from the ground after tt seconds is given by s(t)=−16t2+100t+85.s(t)=−16t2+100t+ 85. Find the velocity of the potato after 0.5s0.5s and 5.75s.5.75s. Find the speed of the potato at 0.5 s and 5.75 s. Determine when the potato reaches its maximum height. Find the acceleration of the potato at 0.5 s and 1.5 s. Determine how long the potato is in the air. Determine the velocity of the potato upon hitting the ground.
