Physics

  1. A stonemason is dragging a 60-kg marble block 4 m across a floorby pulling on a rope attached to the block. He pulls with ahorizontal force of 210 N. The coefficient of kinetic frictionbetween the block and the floor is 0.30.  The next fivequestions have to do with this scenario.  Draw yourself afree-body diagram on the block.

    How much work was done by the stonemason in dragging thisblock?

    a.

    100 J

    b.

    560 J

    c.

    840 J

    d.

    1230 J

  2. Add up the y-components, ΣFy, and determine thenormal force the floor exerts upward on the block.

    a.

    588 N

    b.

    345 N

    c.

    279 N

    d.

    126 N

  3. Using your result from above, calculate the kinetic frictionalforce between the block and the floor.

    a.

    45.6 N

    b.

    56.7 N

    c.

    98.5 N

    d.

    176.4 N

Determine the work done by friction.

  1. a.

    345.2 J

    b.

    -705.6 J

    c.

    -980.1 J

    d.

    1257.9 J

  2. Add up the x-components, ΣFx , and determine theblock's acceleration.

    a.

    3.7 m/s2

    b.

    0.91 m/s2

    c.

    0.56 m/s2

    d.

    0.38 m/s2
