Two teams of nine members each engage in a tug of war. Each of the first team’s members has an average mass of 67 kg and exerts an average force of 1349 N horizontally, on the ground. Each of the second team’s members has an average mass of 71 kg and exerts an average force of 1364 N horizontally, on the ground.(a) What is the acceleration of the two teams?
(b) What is the tension in the section of rope between the teams?

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
