Determine the final velocity of a solid cylinder of a 75mm diameter with a mass of 1.4kg if it is moving along a slope of 250. The total distance travelled down the slop is 11.8m
This is an energy balance problem. You calculate the change in potential energy for a $\displaystyle 1.4$ kg mass when it is lowered through $\displaystyle h=11.8 \sin(25^{\circ})$ and equate this to the kinetic energy gained by the cylinder, which is the sum of the translational and rotational KEs.
