a worker applies a horizontal force to the top edge of a crate to get it to tip (rotate) forward. if the crate has a mass of 100kg and is 1.6m tall and 0.80 wide. assume gravity force is applied at the center of the crate, and that there is enough friction with the floor for crate not to slip, so the lower left rib of crate is the axis of rotation. what is the lever arm for the gravity force?

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...

Ugonna stands at the top of an incline and pushes a 100−kg crate to get it started sliding down the incline. The crate slows to a halt after traveling 1.50 m along the incline. (a) If the initial speed of the crate was 1.85 m/s and the angle of inclination is 30.0°, how much energy was dissipated by friction? (b) What is the coefficient of sliding friction?

A 102-kg crate is being pushed across a horizontal floor by a force P that makes an angle of 41.7 ° below the horizontal. The coefficient of kinetic friction is 0.232. What should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?

How much force could you exert on a large crate if you wanted to get it...

How much force could you exert on a large crate if you wanted to get it moving? One thing the answer depends on is whether you can keep your footing. a) Imagine someone on level ground, pushing horizontally against a crate, with enough effort that their feet are about to start slipping. Nevertheless, the crate hasn't started moving. What type of force is the crate exerting on the person pushing on it, and how does the magnitude of this force...

A 38.0-kg crate is being pushed along a horizontal surface. The applied force is 94.0 N directed at an angle of 18.0° below the horizontal and the coefficient of friction is .21. a) Draw a free body diagram for the crate. b) Write expressions for the x and y components of the applied force (no numbers). c) Sum forces in the x and y direction (no numbers). d) Solve: What is the acceleration of the crate?

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...

A rock is projected from the edge of the top of a building with an initial velocity of 40 ft/s at an angle of 53 above the horizontal

A rock is projected from the edge of the top of a building with an initial velocity of 40 ft/s at an angle of 53 above the horizontal. The rock strikes the ground, a horizontal distance of 82 ft from the base of the building. Assume that the ground is 1evel and that the side of the building is vertical. How tall is the building? a) 77 ft (b) 97 ft (c) 90 ft (d) 83 ft

A 35.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.500 and the constant of the spring is k = 6000 N/m. What is the net impulse exerted on...

A 25.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30.0 ◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.400 and the constant of the spring is k = 5000 N/m. How far does the crate compress...
