A cat swipes at a spool of thread, which then rolls across thefloor with an initial speed of 1.5 m/s. The spool deceleratesuniformly to a stop 3 m from its initial position. The spool has aradius of 1.5 cm and rolls without slipping.
a) What is the initial angular velocity?
1.5 /(1.5/100)=100 rad/s
b) Through what total angle does the spool rotate whileslowing to a stop?
c) What is the angular acceleration during this motion?
I don't really know how to do the rest of the parts.
