QUESTION 4 10 points Save Ans Jessica pulls a sled across level ground using a rope. If the force she applies is 100 N directed 30 degrees above the horizontal and the sled travels at a constant speed, how much work has friction done after 20 m? a-4.33 J b. 1730J c.-1730 J

Explanation / Answer

3.solution

The work can be found using the formula:

W = Fd cos

W = Fd cos()

W = Fd*cos(30)

W = (100 N)(20)(0.866)

W = 1732 J

W = 12 000 000 J
