1. Momentum  Two carts of equal mass begin at rest, then a spring between them releases, sending them in opposite directions. After this, do the carts have the same magnitude of momentum? __ Do they have the same speed?__ a)yes, yes b)yes, no c)no, yes d)no, no

2. Momentum  Two carts of UNequal mass begin at rest, then a spring between them releases, sending them in opposite directions. After this, which cart has larger magnitude of momentum? __ Which has larger speed?__ a)neither, neither b)neither, lighter c)heavier, neither d)heavier, lighter

3. Momentum  One cart begins at rest, the other cart is moving toward it with speed, v. They collide and stick together. What is the speed of the two (together) just after they stick together? a)0 b)v c)<v d)>v

4. Calculus  Are you planning to take Calc II next term (winter)? a)yes b)no c)maybe – leaning toward yes d)maybe – leaning toward no
