The experiment is about inelastic collisions. It is two cars and one of them is on a ramp and the other is down the ramp. The top car (A) will be pushed to collide with the bottom car (B). Regarding the experiment described:

1. Suppose the two cars have the same mass (500 g). What do you predict will be the velocities of the two-car system if car A starts down the ramp from a height of 10 cm above the glass and car B starts at rest on the glass?

2. Suppose the two cars have the same mass (500 g). What do you predict will be the velocities of the two-car system if car A starts down the ramp from a height of 3 cm above the glass and car B starts at rest on the glass?

3. Suppose there is a non-negligible amount of friction on car A but not on car B. What will change in the experiment?

Two bumper cars in an amusement park ride collide elastically as one approaches the other directly from the rear. Car A has a mass of 435 kg and car B 495kg, owing to differences in passenger mass. If car A approaches at 4.50m/s and car B is moving at 3.70m/s, calculate (a) their velocities after the collision, and (b) the change in momentum of each.

A bumper car with mass m1 = 114 kg is moving to the right with a velocity of v1 = 4.7 m/s. A second bumper car with mass m2 = 94 kg is moving to the left with a velocity of v2 = -3.7 m/s. The two cars have an elastic collision. Assume the surface is frictionless. 1)What is the velocity of the center of mass of the system? 2)What is the initial velocity of car 1 in the center-of-mass...

2) Two frictionless roller-coaster cars sit atop identical roller coaster tracks. The two roller-coasters meet at the bottom to form a single continuous roller-coaster track. The more massive car has mass M, the less massive has mass m. Neglect air resistance. a) If the two cars are released simultaneously from rest, describe in words where the two cars collide. b) If when they collide, the two cars stick together, calculate the highest height the two cars will ultimately reach after...

Two cars slide on the air track in Regener Hall. The blue car is on the left, has a mass m1 = 5.00 kg, and is moving to the right with a velocity v1i = 3.00m/s. The green car is on the right, has a mass m2 = 2.50 kg, and is also moving to the right with an initial velocity v2i = 2.00 m/s. The two cars collide. (a) If [the coefficient of restitution] B= 1, what are the...

Two cars approach an ice-covered intersection. One car, of mass 1.21 X 10^3 kg, is initially traveling north at 12.1 m/s. The other car, of mass 1.62 X 10^3 kg, is initially traveling east at 12.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. magnitude: ______ direction: _____ north of east

Suppose the two cars had rubber bumpers in the front and back – similar to the bumper cars children (of all ages!) ride at amusement parks. Also, suppose that the cars are sturdy enough that the metal they are made of does not bend during the collision. In this case, the cars would undergo a perfectly elastic collision. Assume just like in the first collision question that the SUV (initially moving to the right) collides into the stationary smart car....

In the experiment, inelastic collision, we crashed one car into the other, making sure the two stuck together (velcro) and traveled together as a unit. For the conclusion, would you expect the force on Car #1 during the interaction to be the same magnitude as the force on Car #2? How did you come to this conclusion? Please explain, Thank you.
