Question1

A car comes to a bridge throughout a storm and finds the bridge washed out. The driver should get to the other side, so he decides to try leaping it with his car. The side the car is on is 20.3 above the river, whereas opposite side is a mere 2.3 above the river. The river itself is a raging torrent 57.0 wide.

How fast have to the car be travelling just as it leaves the cliff in order to just clear the river and land safely on the opposite side?

What is speed of the car just before it lands safely on the other side?

Question2
