Because weight W = M g, the ratio of weights equals the ratio of masses.
(M_m g)/ (M_w g) = [ (p^2 Man )/ (2 K_man)] / [ (p^2 Woman )/ (2 K_woman)
but p's are equal, so
K_m/K_m = (M_w g)/(M_m g) = W_woman / W_man = 450/680 = 0.662
Explanation:
On a position vs time graph (x vs t), displacement is the difference in positions (Δx = x₂ − x₁).
On a velocity vs time graph (v vs t), displacement is the area under the graph (Δx = ∫ v dt).
