Program Explanation Given information: A driver drives at the speed of 25mph and he applied the break at 25mph and the car skids 45 feet before coming to a stop. The driver’s skid marks at the accident scene measured 201 feet. Calculation: The velocity function can be expressed as, v ( t ) = a t + v 0 ....... (1) The position function can be expressed as, y ( t ) = v 0 t + 1 2 a t 2 + t 0 ....... (2) Since initial time is 0sec then the position function can be expressed as, y ( t ) = v 0 t + 1 2 a t 2 The final velocity would be zero as v ( t ) = 0 . Apply the condition v ( t ) = 0 in equation (1) to obtain the value of t 0 . 0 = a t + v 0 t = − v 0 a It is given that the driver drives at the speed of 25mph and he applied the break at 25mph and the car skids 45 feet before coming to a stop. The driver’s skid marks at the accident scene measured 201 feet. Therefore, the conditions are x = 45 , t = − v 0 a and v 0 = 25
