1) A cart with mass m₁ = 3.2 kg and initial velocity of v_1,i = 2.1 m/s collides with another cart of mass M₂ = 4.3 kg which is initially at rest in the lab frame. The collision is completely elastic, and the wheels on the carts can be treated as massless and frictionless. What is the velocity of m₁ in the center of mass frame after the collision?

2) A block of mass M₁ = 3.5 kg moves with velocity v₁ = 6.3 m/s on a frictionless surface. It collides with block of mass M₂ = 1.7 kg which is initially stationary. The blocks stick together and encounter a rough surface. The blocks eventually come to a stop after traveling a distance d = 1.85 m . What is the coefficient of kinetic friction on the rough surface?

An object of mass m1 approaches with velocity v1 another object of mass m2, which is at rest, next to a spring having force constant k. The spring is fixed to a wall and m2 can compress the spring. This is one-dim horizontal collision without friction. We consider two collision scenarios, one which is perfectly inelastic, and the other which is elastic. (a) In the first collision case the object m1 strikes m2 and sticks. Moving together, they compress the...

Imagine cart 1 with initial velocity v1i collides with cart 2 with initial velocity v2i = 0, where they then move together as a single mass (attached by velcro). Sketch the expected center of mass position over time graph. Assume t = 0 corresponds to the moment immediately after the impulse to cart 1 is delivered and assume equal masses (m1 = m2). Ignoring the effects of friction, is the above collision elastic or inelastic? Why?

A linebacker with mass m1 = 90.0 kg running east at a speed v1 = 3.00 m/s tackles a fullback with mass m2 = 100. kg running north at a speed v2 = 5.00 m/s. The linebacker holds on to the fullback after the tackle, so that the collision is perfectly inelastic. The common speed of the players immediately after the tackle is closest to:

-A roller coaster cart of mass (m1=127 kg) initially sits at rest on a track. Once the motor is activated, the cart is accelerated forward (across level ground) until it reaches the bottom of a giant circular loop with a radius of (r1=17.5 m). At this point, the motor is turned off and the cart must "coast" for the remainder of the ride. Assume the track is frictionless and ignore air resistance. At the top of the loop, what is...
