Question 10 A 100 kg sail boat is moving at a constant speed of 10 m/s due west for a distance of 10 m. How much work is done by the net force acting on the boat? OJ 10 J 100 J 100 J A woman lifts a barbell 2 min 1 second. If she lifts the same barbell the same distance in 2 seconds, the work she does is the same half as much twice as much thrice as much If M is the dimensions of mass, L is the dimensions of length, and T is the dimensions of time, the dimensions of energy are the same as those of torque power momentum impulse The Empire State building in New York city stands at about 443.2 m tall.
