It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s², determine the speed of the Jaguar before it began to skid.

A plane has a takeoff speed of 88.3 m/s and requires 1365m to reach that speed. Determine the acceleration of the plane and the time required to reach this speed.
