A block of mass 15.0 kg slides down a ramp inclined at 28.0∘ above the horizontal. As it slides, a kinetic friction force of 30.0 N parallel to the ramp acts on it. If the block slides for 5.50 m along the ramp, find the work done on the block by friction.

    Work is done by friction = - 165 J

    Explanation:

    Given:

    Mass of block (m) = 15 kg

    Ramp inclined = 28°

    Friction force (f) = 30 N

    Distance (d) = 5.5 m

    Find:

    Work is done by friction.

    Computation:

    Work is done by friction = - Fd

    Work is done by friction = - (30) (5.5)

    Work is done by friction = - 165 J
