Handed back Collision Lab.

Went over 7-block elastic collision problem - first the long way and then showing how to do it the easy way. Then did the problem assuming an inelastic collision - the important thing here is to check which blocks actually collide.

Went over RA 5.3

Ballistic Pendulum Lab/Demo/Calculation

Showed how to calculate impulse graphically for a non-constant force.

Gave students time in class to work on worksheet Problems in Momentum.

Assigned WebAssign Hewitt chapter 5 for review (due tomorrow)

Wednesday we will go over any questions on the problem sheet, any questions from WebAssign, and review for the test.

Test scheduled for Thursday.
