The driver of a 600.0 kg sports car, heading directly for a railroad crossing, 300.0 m away, applies the brakes in a panic stop. the car is moving at 40.0 m/s and the brakes can supply a force of 1500 n. a.) how fast will the car be moving when it reaches the crossing? b.) will the driver escape collision with a freight which, at the instant the brakes are applied, is still blocking the road and still requires 11.0 s to clear the crossing?
