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. (Cylinder=1/2MR²)

a) Evaluate the total kinetic energy of the barrel?

b) At the similar 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. Find how far from that point will the barrel travel before it stops?
