A car braked with a constant deceleration of 45ft/s^2 producing skid marks measuring 55 ft before coming to a stop. How fast was the car traveling when the brakes were first applied? Please round the answer to the nearest hundredth.
Vintial^2 - Vfinal^2= -2*acceleration*distance
Vfinal is zero. deacceleration is negative acceleration in the problem statement
thanks a bunch
