- Two teams of nine members each engage in a tug of war. Each of the first team's members has an average mass of 65 kg and exerts an average force of 1350 N horizontally. Each of the second team's members has an average mass of 70 kg and exerts an average force of 1369 N horizontally. a. What is the acceleration (in m/s2 in the direction the heavy team is pulling) of the two teams? b. What is the tension (in N) in the section of rope between the teams?arrow_forward2. A model rocket has a mass of 300 g and an engine that generates 40 N of thrust. The rocket is launched vertically, so that the trust is directed straight up. It is a windy day, and the wind generates a constant force of 5 N horizontally to the east; you can ignore any other forces from the air such as air drag for this problem. A. Draw a free body for this rocket shortly after launch while the engine is firing. B. What is the net force on the rocket after launch while the engine is firing?

The rocket is initially 80 m above the planet's surface and is descending downward at 50 m/s. The mass of the rocket is 2500 kg. The rocket will land on the surface with a final velocity of 0. Our goal is to find the upward thrust force on the rocket to make this happen. Draw a motion diagram . Find the deceleration of the rocket. Draw force diagram for the rocket. Show the net force.

The cloth exerts a friction force of 0.100 N on the mug and is pulled with a constant acceleration of 3.00 m/s2. How far does the mug move relative to the horizontal tabletop before the cloth is completely out from under it? Note that the cloth must move more than 15 cm relative to the tabletop during the process.arrow_forward
