Two students are arguing over the size of the net force acting on a 450kg box when a person pulls it at a constant speed of 7.1m/s across the level ground. James says that the applied force from the person is greater than the friction force but Tony says that the two are equal. Explain who you think is right and use physics equations to support the argument. Thanks in advance!

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
