A worker is trying to push a crate across the floor in the rightward direction with a horizontal force of 15N. The crate does not move. The mass of the crate is 10kg. The coefficient of static friction is 0.25, and the coefficient of kinetic friction is 0.15. (1) what is the friction on the crate? Give both magnitude and direction of the friction. (2) He then pulls the right edge of the crate with a force of 50N at an angle \Theta =30degrees above the x-axis. Does the crate move? Justify your answer quantitatively. (3) what is the acceleration of the crate if it moves? (4) what is the work done by the workers force when the crate moves 4 meters? (5) what is the work done by the gravitational force in that 4-meters distance? (6) What us the thermal energy dissipated during the move?

KINETIC FRICTION You’re trying to move a large, 60kg wooden crate across a wooden floor. (μs = 0.35). YoYou try again pushing with 120N perfectly horizontally. Again you realize you can exploit the relationship between normal force and friction to make your life easier, and decide to attach a rope and drag the box, pulling up with at an angle of 10°. You easily match the former acceleration of 0.04 m/s2 . A. Draw a free-body diagram for the box. B....

Work on a sliding crate. A worker pushes a 47.0 Kg crate across a level horizontal floor by applying a constant force of exactly 150.0 N at an angle of 23.0 degrees below the horizontal. The crate begins at rest and ends 15.0m from where it started traveling at 2.6m/s A. What is the work done by the applied force as the crate moves across the floor? B What is the work done by the friction force as the crate...

A 1,300-N crate is being pushed across a level floor at a constant speed by a force F of 390 N at an angle of 20.0° below the horizontal, as shown in the figure a below. Two figures show a side view of a crate positioned upon a horizontal surface. Figure (a): An arrow pointing downward and to the right is labeled vector F and forms an angle of 20° below the horizontal as it approaches the upper left edge...

A man pulls a crate of mass 61.0 kg across a level floor. He pulls with a force of 180.0 N at an angle of 29.0° above the horizontal. When the crate is moving, the frictional force between the floor and the crate has a magnitude of 122.0 N. If the crate starts from rest, how fast will it be moving after the man has pulled it a distance of 2.50 m?
