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...
A particle is traveling in a straight line at a constant speed of 25.0 m/s. Suddenly, a constant net force of 15.0 N acts on it, bringing it to a stop in a distance of 62.5 m.
1.What is the direction of the net force?
A.Same as the weight of the particle.
B.Same as the direction of motion of...
