A certain cable car is San Francisco can
stop in 10 s when traveling at maximum speed. On one occasion, the
driver sees a dog a distance d m in front of the car and slams on
the brakes instantly. The car reaches the dog 7.92 s later, and the
dog jumps off the track just in time. If the car travels 3.83 m
beyond the position of the dog before coming to a stop, how far was
the car from the dog? [Hint: You will need three equations.] m

A San Francisco cable car is pulled by a cable running under the street. The cable moves at a constant speed of 9.50 mi/hr. The person who operates the cable car (called a gripman) operates a grip that grabs hold of the moving cable. (See Figure 2.) The gripman can allow the cable to slide through the grip so that the car can move at a speed that is slower than the cable. In Figure 2 the...
A driver is traveling at 30.0 m>s when he sees a moose crossing the road 80.0 m ahead. The moose becomes distracted and stops in the middle of the road. If the driver of the car slams on the brakes, what is the minimum constant acceleration he must undergo to stop short of the moose and avert an accident?

11. A driver traveling at 27.8m/s tries to stop the car and finds that the brakes have failed. The emergency brake is then pulled and the car comes to a stop in 130 m. Find the car's deceleration.
