A trailer is hitched to a car. The car and trailer are traveling at when the driver applies the brakes on both the car and the trailer. Knowing that the braking forces exerted on the car and the trailer are and , repectively, determine: (a) the distance traveled by the car and trailer before they come to a stop and (b) the horizontal component of the force exerted by the trailer hitch on the car.

Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s^2. It takes the driver of car A 0.75 s to react. When he applies his brakes, he decelerates at 15 ft/s^2. Determine the minimum distance d between the cars so as to avoid a collision.

Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s^2. It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 15 ft/s^2. Determine the minimum distance d between the cars so as to avoid a collision.

A 2004 Prius with a 150-lb driver and no passengers weighs 3071 lb. The car is initially at rest. Starting at t = 0, a net horizontal force Fx(t) in the +x-direction is applied to the car. The force as a function of time is given in Fig. P8.100.

(a) For the time interval t = 0 to t = 4.50 s, what is the impulse applied to the car?

(b) What is the speed of the car at t = 4.50 s?

(c) At t = 4.50 s, the 3500-N net force is replaced by a constant net braking force Bx = -5200 N. Once the braking force is first applied, how long does it take the car to stop?

(d) How much work must be done on the car by the braking force to stop the car?

(e) What distance does the car travel from the time the braking force is first applied until the car stops?Ā
