Question

1. If the supplied force F = 125 N, determine the velocity of the 25kg block A when it has risen 2 m, starting from rest.

1a. How would our approach to this question change if there were a spring instead of a 25kg block, as depicted below?

1b. Why is it valid to neglect the small mass and friction of the pulleys in this system, and how does this simplification contribute to the overall analysis? How does the calculation procedure change if the friction of the pulleys is not neglected?
