Problem
A car is approaching a wall with a trajectory that is perpendicular to the wall. The driver, however, wishes to approach the wall safely. Find the car's speed as a function of time, so that the distance between the car and the wall is, at every moment, the same as the distance the car would travel with its instantaneous speed in T=2s.
