The longest recorded skid marks on a public road were left by a jaguar in a 1960 auto accident in USA and measured an astounding 290 m long. Assuming that the car had an average accelaration of -3.9 m/s^2 determine the jaguar's initial speed before the skid started.

Well you know distance, final velocity, and acceleration. There is a very simple kinematics equation to find this.
vf^2-v0^2=2*a*x
where vf is the final velocity, v0 is initial velocity, a is acceleration, and x is distance traveled. Simply solve for v0 and you have the answer.
