A crash test is performed between an SUV A and a 2500-lb compact car B. The compact car is stationary before the impact and has its brakes applied. A transducer measures the force during the impact, and the force P varies as shown. Knowing that the coefficients of friction between the tires and the road are μs= 0.9 and μs = 0.7, determine (a) the time at which the compact car will start moving, (b) the maximum speed of the car, (c) the time at which the car will come to a stop.
