A 2000 kg car strikes a wall at 15 m/s and comes to a stop in .15 seconds. With how much force did the car strike the wall? Please show all work.
A 2500-kg car traveling at 6.0 m/s runs into a wall. The complete wall is not affected, but the car crumples such that in the time interval from the instant of impact to the instant at which the car comes to rest, the center of mass travels forward 0.4 meters. A) What is the magnitude of the average force exerted on the car? B) What is the time of the crumple?
1. A 12,000 kg railroad car, intially traveling at 1.6 m/s, strikes three identical and connected railroad cars, initially at rest. The track is horizontal and frictionless. After the collision, all four cars move together at the same velocity. A. Determine the final speed of the cars. (0.4 m/s). B. Assuming the collision took 1.5 seconds, calculate the average force of collision. C. How much non-conservative work was done during the collision? (-11500 J)

The driver of a 1.19 103 kg car traveling on the interstate at 35.0 m/s (nearly 80.0 mph) slams on his brakes to avoid hitting a second vehicle in front of him, which had come to rest because of congestion ahead. After the brakes are applied, a constant kinetic friction force of magnitude 7.96 103 N acts on the car. Ignore air resistance. (a) At what minimum distance should the brakes be applied to avoid a collision with the other...
A 0.500 kg hammer is moving horizontally at 6.50 m/s when it strikes a nail and comes to rest after driving it 1.00 cm into a board. (a) Calculate the duration of the impact in seconds. (b) Calculate the impulse imparted. (c) What was the average force exerted on the nail?
A 5,000 kg truck traveling at 50 m/s encounters a wall and comes to a stop as it crashes into the wall. The force of the crash was 60,000 N. How long was the crash?
A 3.6-kg steel ball traveling
at 8.0 m/s hits a wall at an angle of ? = 61.0o as shown in the
figure. It bounces off the wall with the same speed and same angle.
If the ball was in contact with the wall for 0.14 seconds, what was
the magnitude of the average force exerted on the ball by the
wall?
17) A 7700 kg boxcar traveling at 14.0 m/s strikes a second car at rest. The two stick together and move off with a speed of 5.0 m/s. What is the mass of the second car? A) 14000 kg B) 13000 kg C) 13860 kg D) 13720 kg E) 12970 kg
A 2,000 kg car traveling north at a velocity of 45m/s strikes 2,200 Kg car traveling west at 50 m/s. The two vehicles strike each other and stick together. As a single combined mass they slide across the pavement which has a coefficient of kinetic friction 0.07. What is the displacement from the point of impact to the final resting place of the cars? (How long does it take for them to come to rest?) A 200 Kg ball is...
