What is the final angular speed of the barrel? >
A barrel is given a downhill rolling start of #1.5" rad/s"# at the top of a hill. Assume a constant angular acceleration of #2.9" rad/s"^2#

If the barrel takes #11.5" s"# to get to the bottom of the hill, what is the final angular speed of the barrel?

What angular displacement does the barrel experience during the #11.5" s"# ride?
