Gce Model Questions Vol1 2024 Agricultural Science Question 8 diagram

The diagram shows a simple block‑and‑tackle system consisting of one fixed pulley and one movable pulley used to lift a sack of mass 150 kg. The free end of the rope is pulled vertically with a force \(F\).\n(a) Determine the minimum pulling force required to start lifting the sack (i.e., to overcome its weight).\n(b) If the farmer applies a pulling force of 1200 N, calculate the upward acceleration of the sack.

Answer Options

A. Minimum force ≈ 736 N; acceleration ≈ 4.0 m\/s² upward
Correct Answer B. Minimum force ≈ 736 N; acceleration ≈ 6.2 m/s² upward
C. Minimum force ≈ 800 N; acceleration ≈ 5.0 m\/s² upward
D. Minimum force ≈ 600 N; acceleration ≈ 7.5 m\/s² upward
Correct Answer
B
Correct Option:
Minimum force ≈ 736 N; acceleration ≈ 6.2 m/s² upward
