A car 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 the car is on is 23.3 m above the river, while the
opposite side is a mere 6.1 m above the river. The river itself is a raging
torrent 70 m wide.
How fast in m/s) should the car be traveling just as it leaves the cliff in
order just to clear the river and land safely on the opposite side?
What is the speed (in m/s) of the car just before it lands safely on the
other side?
