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 1.0-kg standard cart collides on a low-friction track with cart A. The standard cart has an initial xcomponent of velocity of +0.40 m/s, and cart A is initially at rest. After the collision the x component of velocity of the standard cart is +0.20 m/s and the x component of velocity of cart A is +0.70 m/s . After the collision, cart A continues to the end of the track and rebounds with its speed unchanged. Before the carts...
