Kevin works as a janitor, and he is pushing a fully-loaded recycling bin that weighs 557 N across the floor. He applies a force of 410 N at an angle of 15° below the horizontal. The coefficient of kinetic friction between the recycling bin and the floor is 0.46. How long does it take him to move the bin 6.5 meters, assuming the bin starts from rest?   1.98 s   3.77 s   1.02 s   2.85 s

A delivery company has unloaded a 35 kgkg crate in your driveway. The coefficient of static friction between the crate and the driveway surface is μsμs = 0.30. The coefficient of kinetic friction is μkμk = 0.20. In order to move the crate, you apply a horizontal force of magnitude FF by pushing on it. As a result, the crate slides with an acceleration of 5.0 m/s2m/s2. What is the force F? Express your answer with the appropriate units.

A 129 kg crate is sitting at the top of a ramp, which is inclined at an angle of 20 degrees with respect to the horizontal. Someone gives the crate a quick shove to get it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is ls = 0.23. What is the magnitude of the acceleration (in m/s?) of the crate?

A man is trying to move an object (m 14.0 kg) by pulling upward on the rope at an angle of 53° above the horizontal. The coefficient of kinetic friction is 0.300 between the object and the ground. The tension in the rope is 150 N. What is the acceleration of the object? 53 O 6.08 m/s2 O 6.86 m/s2 O 3.50 m/s2 7.77 m/s2 6.82 m/s2

You want to move a heavy box with mass 30.0 kg across a carpeted floor. You pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 N, causing the box to move horizontally. The force of friction between the moving box and the floor has magnitude 41.5 N . Q: A normal walking speed is around 2.0 m/s . How much time t does it take the box to reach this speed if it has the acceleration 5.54 m/s2?

An object with mass 5.00 kg is being pushed up an inclined plane with a constant force F. The plane makes an angle of 30.0° with respect to the horizontal. The object is moving with constant velocity. The coefficient of kinetic friction between the object and the surface is 0.300. What is the magnitude of this force? * O 12.3 N 19.4 N 24.6 N O 37.3 N

A cord pulls an 7.0 kg block across a horizontal floor at constant velocity.The coefficient of kinetic friction between the block and the cord is µk = 0.21. What is the tension in the cord?     69 N     28 N     55 N     14 N

You place a crate of mass 31.6 kg on a frictionless 3.00-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.34 s after you released it. What is the angle of the incline?   A 24.9 degrees   B 19.9 degrees   C 29.9 degrees   D 44.9 degrees
