help pls A horizontal force pushes on a 50 kg crate resting on the floor. Once the crate is moving, kinetic friction acts on it. The coefficient of kinetic friction is 0.40. Determine the acceleration of the crate (in m/s) if the applied force is 200 newtons,
Figure 5 shows a crate has a mass of 50 kg and the coefficient of static friction between the crate and the plane is us = 0.25. (1) Determine the minimum horizontal force P required to hold the crate from sliding down the plane. (8 marks) Determine the minimum force P required to push the crate up the plane. (8 marks) (11) P 30° Figure Q5
A large crate is at rest on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.500. A force F⃗ is applied to the crate in a direction 30.0∘ above the horizontal. The minimum value of F required to get the crate to start sliding is 410 N. Part A What is the mass of the crate? Express your answer with the appropriate units.
Problem 04 ed A 244-kg crate is being above the horizontal. The coefficient of kinetic friction is 0.2. If the crate is moved a distance of 45 m calculate across a horizontal floor by a force P that makes an angle 8-32.5 P 150ON 244 Kg [Hint draw a free body diagram and find the friction force] a) the work done by the net force. b) If the block was initially at rest compute its speed upon reaching 45 m
If you push with a horizontal 650-N force to a 90-kg crate initially at resting on the floor, what must acceleration be? The static and kinetic energy coefficient of friction are us- 0.4, uk= 0.25 respectively.
1. You have one last large 50 kg crate to move from your apt to your car and your inconsiderate roommate took the cart with him. So in order to move the crate, you tie a string to it and pull at an angle of 30° above the horizontal such that you move the crate along at a relatively constant speed. The coefficient of kinetic friction between the floor and the crate is 0.2 and the coefficient of static friction...
A mass of 9 kg rests on a floor with a coefficient of static friction of 1.25 and coefficient of kinetic friction of kinetic friction of 0.1. One force is applied vertically downward of 10 Newtons and another force is applied at an angle of 15 degrees below the horizontal. Calculate what the magnitude this force needs to be in order to begin to move the mass. If the same amount of force is applied at the same angle above...
