Starting at a certain speed, a bicyclist travels 200m. Suppose the bicyclist undergoes a constant acceleration of 1.20m/s squared. If the final speed is 25.0m/s, what was the bicyclists initial speed?
V2^2 = V1^2 + 2*a* s V2 = final velocity V1 = initial velocity a  = acceleration s  = displacement covered 25^2 = V1^2 + 2 * 1.2 * 200 625  = V1^2  + 480 625 - 480 = V1^2 145      = V1^2 So V1 = Sqrt(145) = 12.04 m/s
