A BMW of mass 2000 kg is traveling at 42 m/s. It approaches a 1000 kg Volkswagen going 25 m/s in the same direction and strikes it in the rear. Neither driver applies the brakes. Ignore the relatively small force on the cars due to the road and due to air resistance. (a) If the collision slows the BMW down to 33 m/s, what is the speed of the VW after the collision? (b) During the collision, which car exerts a larger force on the other, or are the forces equal in magnitude? Explain.

Car A has a mass of 2000 kg and approaches an intersection with a velocity of 38 m/s directed to the east. Car B has a mass of 3500 kg and approaches the intersection with a velocity of 53 m/s directed 63° north of east. The two cars collide and stick together after the collision. Calculate the velocity after the collision.

Traveling at 40.2 m/s, a driver applies the brakes to his fast-moving car and skids out of control on a wet concrete horizontal road. The 2000 kg car is headed directly toward a student waiting to catch a bus to campus who is standing 58.0 m down the road. Luckily, Superman is flying overhead and surveys the situation. Knowing that the coefficient of kinetic friction between rubber and rough wet concrete is .800, he determines that friction alone will not...

A 940 kg car traveling east at 12.3 m/s collides with a 670 kg car traveling north at 20.3 m/s . The cars stick together. Assume that any other unbalanced forces are negligible. A) In what direction does the wreckage move just after the collision? B) What is the speed of the wreckage just after the collision?

A car of mass 772 kg is traveling 26.4 m/s when the driver applies the brakes, which lock the wheels. The car skids for 4.47 s in the positive x-direction before coming to rest. HINT (a) What is the car's acceleration (in m/s2)? (Indicate the direction with the sign of your answer.) m/s2 (b) What magnitude force (in N) acted on the car during this time? N (c) How far (in m) did the car travel? m

A driver on Route 15 is traveling at 50 mph (~22 m/s) when they see a dog in the road ahead. The driver’s reaction time to apply the brakes is 1.5 s. As the driver nears the dog they honk the horn and thankfully the dog runs to safety on the side of the road. The car finally comes to a stop 5 s after applying the brakes and 4 m past where the dog had been standing. How far...

Traveling at a speed of 15.8 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.540. What is the speed of the automobile after 1.19 s have elapsed? Ignore the effects of air resistance.
