Melvin pulls a sled across level snow with a
force of 345 N along a rope that is 31◦
above
the horizontal.
If the sled moved a distance of 34.5 m, how
much work did Melvin do?

  1. Cant be solved, unless something else is known, which is the acceleration the sled is undergoing. If it is not accelerating, then
    work=345*cos31*distance

  2. No you're good Bob. It can accelerate and the work will still be the same.
