Observe a bouncy collision (also known as an elastic collision) and discuss whether or not the outcome was what you predicted it to be. Use carts with spring plungers or magnets. If not, draw a new sketch in the space that follows with arrows indicating the magnitudes and directions of the velocities. What is the apparent relationship between the final velocities and

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
