Chapter 9, Problem 86GP
Amplified Rebound Height Two small rubber balls are dropped from rest at a height h above a hard floor When the balls are released, the lighter ball (with mass m) is directly above the heavier ball (with mass M) Assume the heavier ball reaches the floor first and bounces elastically, thus, when the balls collide, the ball of mass M is moving upward with a speed u and the ball of mass m is moving downward with essentially the same speed. In terms of h find the height to which the ball of mass m rises after the collision (Use the results given in Problem 83, and assume the balls collide at ground level.)

3. You would like to deposit material within a high aspect ratio trench. What approach would you
use and why?
4. A person is setting up a small clean room space to carry out an outreach activity to educate high
school students about patterning using photolithography. They obtained a positive photoresist, a
used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask
with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full
resist gets developed, and they are unable to transfer the pattern onto the resist. Help them
troubleshoot and find out why pattern of transfer has not been successful.
