11 In three situations, a single force acts on a moving particle. Here are the velocities (at that instant) and the forces: (1) =(-41) m/s, F= (61-201) N; (2) = (2-3)) m/s, F=(-2) + 7k) N; (3) v = (-3i+j) m/s, F= (21+ 6j) N. Rank the situations according to the rate at which energy is being trans- ferred, greatest transfer to the particle ranked first, greatest trans- fer from the particle ranked last.

Question
11 In three situations, a single force acts on a moving particle. Here are the velocities (at that instant) and the forces: (1) v = (-4î) m/s, F = (6ỉ – 20j) N; (2) ▼ = (2i – 3j) m/s, F = (-2j + 7k) N; (3) ▼ = (-3î + j) m/s, F = (2î + 6j) N. Rank the situations according to the rate at which energy is being trans- ferred, greatest transfer to the particle ranked first, greatest trans- fer from the particle ranked last.
