A cylindrical barrel with a radius of 30 centimeter and a mass of 75 kilogram rolls across a warehouse floor without slipping. The speed of the barrel's center of mass is 8.0 m/s.
A. Calculate the total kinetic energy of the barrel?
B. Determine at the same moment the speed of the barrel was noted to be 8.0 m/s it was also noted to be slowing down with an angular acceleration of - 0.30 rad/s2. Determine how far from that point will the barrel travel before it stops?
