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?

2 answers

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