You need to push a box across carpet. The box and its contents have a mass of 75 kg. The coefficients of static friction and kinetic friction between the box and the carpet are 0.60 and 0.40, respectively. A. You push horizontally on the box with a force of 300 N. Draw a free-body diagram for this scenario. What is the magnitude of all the individual forces that act on the box? B. You now push horizontally on the box...
Question 1 5 pts A large heavy box sits on a ramp. You need to push it up the ramp. The box does not move. The total mass of the box (and its contents) is M = 45 kg and the applied force is P= 100 N, and the incline of the ramp is 0 = 25 degrees, what are the magnitudes for the following forces? the normal force acting on the box [Choose] the frictional force acting on the...
answer all questions pleaseeee
Problem# 5: A box with mass 12.0 kg moves on a ramp that is inclined at an angle of 60.0 above the horizontal. The coefficient of kinetic friction between the box and the ramp surface is u-0.380, a) Draw a free body diagram b) Express all required equations c) Calculate the magnitude of the acceleration of the box if you push on the box with a constant force F- 150.0 N that is parallel to the...
You need to push a heavy box across a rough floor, and you want to minimize the average force applied to the box during the time the box is being pushed. Which method for pushing results in the minimum average force being applied to the box? Keep pushing the box forward at a steady speed, Push the box forward a short distance, rest, then repeat until finished, Push the box so that it accelerates forward at a constant rate. This...

You push a crate of mass m up a ramp inclined at an angle A with a force parallel to the ramp but of varying magnitude. The coefficient of friction between the crate and ramp is u, and the speed of the crate, which starts from rest, is v at the end of the ramp of length d. a) Use the work-energy theorem to find the work done by the non-constant force in moving the crate up the ramp. b)...
A 2.3 kg box, starting from rest, is pushed up a ramp by a 10 N force parallel to the ramp. The ramp is 2.0 m long and tilted at 17 degrees. The speed of the box at the top of the ramp is 0.80 m/s. (Consider the system to be the box + ramp + earth.) A.) What is the equation for conservation of energy for the system? B.) How much work W does the force do on the...
Question 4 8 pts A box of mass m = 7 kg is being pushed up a ramp that is angled 15 degrees above horizontal. The pushing force P = 49 N. The coefficient of kinetic friction is 0.215. At a certain time the velocity of the box moving up the ramp is 1.0 m/s. How far will the box been pushed during the next 3.0 seconds assuming the same pushing force is applied? In your solution you must show:...
A 30-kg box is at rest on a horizontal floor with friction coefficients μs = 0.65 (static) and μk = 0.55 (kinetic). You push on the box HORIZONTALLY (parallel to the floor) with varying applied force. For each applied force below, find the magnitude of the friction force exerted by the floor on the box (in Newtons), and state whether the friction is static or kinetic. (a) Applied force 100 N. (b) Applied force 150 N. (c) Applied force 190...
