Question

Calculate the work done. A tractor pulls a heavy log with a force of 100 pounds. The log moves 3 feet.

Answer 1

f = m*a (force equals mass and acceleration)

And since we don't know the actual mass then it's- 100=(m)*3

So when the tractor pulled the log that is, 100 pounds and it only moved 3 feet.

But calculating it (by multiplication) equals to 300 ft-lbs, so therefore it can't be 130 ft-lbs.

So by my guess, it's 300 ft-lbs, since it's impossible and strange to even reach some number as the first and second one.
