    Science Question Number 2

    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 1.4 kg mass when it is lowered through 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.

    Hi CB,

    Thanks very much for the reply that has helped greatly...

    The final velocity I get is 8.07 (is this correct?)

    Best Regards,
    HNC
