A tugboat tows a ship with a constant force of magnitude F1. The increase in the ship’s speed in a 10-s interval is 4.0 km/h. When a second tugboat applies an additional constant force of magnitude F2 in the same direction, the speed increases by 16 km/h in a 10-s interval.
How do the magnitudes of F1 and F2 compare?
(Neglect the effects of water and air resistance.)
A.F2 = 3F1
B.F2 = 4F1
C.F2 = 2F1
D.F2 = F1
E.F2 = (1/4)F1
This is making me mad!! I can't get the thing.
