Chapter 7

#4

Be sure to convert units first. Answer with 2 SF.

#12

The distance travelled by the coin is the same as the "s" in equation 7.1 or the displacement in the five equations of motion with constant acceleration.

#16

There is only centripetal acceleration here, not tangential acceleration.

#18

For part (a), simply set the centripetal acceleration equal to 0.500 and solve for v.

#26

Include both tension and centrifugal force when considering this problem. Similar to #48, in principle. See also #43 and #50.

#32

I'll give you some hints on this problem in class. There are a couple of tricks you can use to make it very easy.

#36

Answer with 3 SF.

#38

Answer with 3 SF.

#48

Similar to #26.
