1. A drawbridge over a river crossing of width 2L is divided into two halves (each of length L) which can open to allow boats to pass underneath. When each half of the bridge is at an angle to the horizontal, a stunt car races up one side with speed v. If the car is to cross the empty gap and land on the other side of the bridge, calculate the minimum value that must have, in terms of 0, L and g. 1.
