Consider two cars traveling on the highway, one behind the other. They are both moving at the same initial velocity, vi-29.1 m/s, with the first car a distance d in front of the second car. ("d" is the distance from the front bumper of the second car to the back bumper of the first car.) At some time the driver of the first car hits the brakes and comes to a stop with...

22. Two cars are driving down a straight country road when the driver of the first car (traveling at speed vi v sees a deer crossing the road in front of her. She quickly applies her brakes, causing her car to slow down with a (negative) acceleration a--2a. The second car is a distance D behind her and is traveling at an initial speed v2 v. Its driver immediately applies his brakes as well-assume at the same time as the...

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...

Two cars are traveling along a straight line in the same direction, the lead car at 25.7m/s and the other car at 29.2m/s. At the moment the cars are 39.7m apart, the lead driver applies the brakes, causing her car to have an acceleration of -1.99m/s2. How long does it take for the lead car to stop? What is the distance it travels during this time? Assuming that the chasing car brakes at the same time as the lead car,...

TWO cars are traveling along a straight line In the same direction, the lead car at 24.1 m/s and the other car at 29.0m/s. At the moment the cars are 41.1m apart, the lead driver applies the brakes, causing her car to have an acceleration of -2.09m/s^2. How long does it take for the lead car to stop? What is the distance it travels during this time? Assuming that the chasing car brakes at the same time as the lead...

Two cars are traveling in the same lane in the same direction. They are 120 ft apart and are both traveling at 60 mph. The roadway is level. The leading car hits a disabled milk truck and comes to an instatenous stop. The perception-reaction time of the driver in the trailing car is ½ second. The driver of the trailing car locks the brakes and skids into the lead car. The coefficient of friction between the roadway and skidding tires...

Question 8 1 pts The driver of a car wishes to pass a truck that is traveling at a constant speed of 20.0 m/s. Initially, the car is traveling at a speed 25.0 m/s and its front bumper is a distance 24.0 m behind the truck's rear bumper. The car begins accelerating at a constant acceleration 0.6 m/s2, then pulls back into the truck's lane when the rear of the car is a distance 26.0 m ahead of the front...

Consider a system of two toy rail cars (i.e.. frictionless masses)- Suppose that car 1 has mass 6 kg and is traveling at 3 m/s toward the other car- Suppose car 2 has mass 3 kg and is moving toward the other car at 9 m/s. There is a bumper on the second rail car that engages at the moment the cars hit and does not let go (it connects the two cars). The bumper acts as a spring with...
