Leaping the River I. A car traveling on a level horizontal road comes to a bridge during a storm
and finds the bridge washed out. The driver must get to the other side, so he decides to try leaping
it with his car. The side of the road the car is on is 21.3 m above the river, while the opposite
side is a mere 1.8 m above the river. The river itself is a raging torrent 61.0 m wide.
(a) How fast should the car be traveling at the time it leaves the road in order just to clear the
river and land safely on the opposite side?
(b) What is the speed of the car just before it lands on the other side?
