When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1880-kg car traveling to the right 1.64 m/s at collides with a 1445-kg car going to the left at 1.09 m/s. Measurements show that the heavier car's speed just after the collision was 0.215 m/s in its original direction. You can ignore any road friction during the collision.
What was the speed of the lighter car just after the
collision?
m/s
(b) Calculate the change in the combined kinetic energy of the
two-car system during this collision.

When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1750 kg car traveling to the right at 1.40 m/s collides with a 1450 kg car going to the left at 1.10 m/s . Measurements show that the heavier car's speed just after the collision was 0.270 m/s in its original direction. You can ignore any road friction during the collision. Part A What was...

All collisions will be completely elastic - that is, the total kinetic energy of the system will be constant throughout. Also, the collisions are entirely one-dimensional, with all motion taking place in either the northward or southward direction. The setting: a room with a frictionless floor. A block of mass 1 kg is placed on the floor and initially pushed northward, whereupon it begins sliding with a constant speed of 5 m/s. It eventually collides with a secondary, stationary block...

5. An automobile of mass 1500 kg moving at 25.0 m/s collides with a mass 4500 kg at rest. The bumpers of the two vehicles lock together the crash. a. Compare the force exerted by the car on the truck with that exerted truck on the car during the collision. Is one force larger than the are they equal in magnitude to each other? b. What is the final velocity of the car and truck just after the collision? Show your calculations. 6....
A railroad car of mass 2.42 × 104 kg is moving with a speed of 3.84 m/s. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the same direction with an initial speed of1.92 m/s.

Police Report: There were two individuals involved in the accident. No other passengers were present and no other vehicles were involved. There was a truck of mass 1,936 kg traveling Southbound on H and a compact car of mass 1,077 kg travelling Northbound on HWY 26. A bystander claims to have watched the vehicles collide and slide Southbound off the road into a tall grassy ditch. The grass was determined to have a coeficient of friction of 0.6, while the...
