A daredevil jumps a canyon 9.6 m wide. To do so, he drives a car up a 18° incline. (The daredevil lands on the other side of the canyon at the same elevation as takeoff.)
(a) What minimum speed must he achieve to clear the canyon?
(b) If the daredevil jumps at this minimum speed, what will his speed be when he reaches the other side?
