1. You want to contrast a physical pendulum with a period of 4.0s at a location where g= 9.8s/s^2.

a. What length of simple pendulum having this period?

b. Suppose the physical pendulum must be mounted in a case that is not more than 0.5m high. Can you devise a physical pendulum having a period of 4.0s s that will satisfy this requirement?

2. a block with mass M rests on a frictionless surface and is connected to a horizontal spring of force constant k. The other end of the spring is attached to a wall. A second block with mass m rests on top of the first block. The coefficient of static friction between the block is µs. find the maximum amplitude of oscillation such that the top block will not slip on the bottom block?
