Problem

For the three cases listed below, the same block is acted upon by different constant forces over the entire displacement. Rank the magnitude of work done in the three cases from greatest to least. Case P: F=12 NF = 12\,\text{N}, s=3 ms = 3\,\text{m}, θ=0∘\theta = 0^\circ Case Q: F=15 NF = 15\,\text{N}, s=2 ms = 2\,\text{m}, θ=60∘\theta = 60^\circ Case R: F=10 NF = 10\,\text{N}, s=4 ms = 4\,\text{m}, θ=30∘\theta = 30^\circ (a) R >> P >> Q (b) P >> R >> Q (c) Q >> R >> P (d) P >> Q >> R
