A force F is used to raise a 4-kg mass M from the ground to a height of 5 m
![[IMG]]()
What is the work done by the force F? (Note: sin 60o = 0.87; cos 60o = 0.50. Ignore friction and the weights of the pulleys.)
50 J
100 J
174 J
200 J
Answer: D
Explanation: Work is the product of force and distance. The easiest way to calculate...
