Test: MAKE UP EXAM G) Score: :3 of1 point Let G = 4i 9, where the graphs of f and g are shown in the gure to the right. Find the following derivative. 3; 615) | T3311: MAKE UP EXAM Question 3 Score: Oof1 point 8}) Submit Test The distance an object falls (when released from rest, under the Inuence of Earth's gravity, and with no air resistance) is given by d(t)= 16t2, where d is measured in leet and t is measured in seconds. A rock climber sits on a ledge on a vertical wall and carefully observes the time it takes for a small stone to fall from the ledge t0 the ground. a. Compute d'(t). What units are associated with the derivative. and what does it measure? I). If it takes 5.6 s for a stone to fall to the ground, how high is the ledge? How fast is the stone moving when it stn'kes the ground (in miles per hour)? a. d'(t) : The units associated with the derivative are Y and it measures the Y of the stone. b. The ledge is feet high. (Round to the nearest integer as needed.) The stone is moving at milhr when it strikes the ground. (Round to the nearest integer as needed.) Test: MAKE UP EXAM 0 be given.
