A student is pulling a crate with a mass of 20.0 kg along a horizontal rough floor with a rope that's inclined at an angle θ = 30.0∘ above the horizontal as shown. The tension force is measured to be 150 N. The coefficients of friction between the crate and the floor are μs = 0.35 and μk = 0.20. What is the magnitude of the acceleration of the crate, in m/s2? Use g = 10.0 m/s2. ((Compare the result from the previous homework when there was no friction, does the answer make sense?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

4. (20 points) Two blocks are tethered together with a rope. Block A has mass 2 kg, Block B has mass 10 kg. A force F = 50 N at an angle Θ = 20 deg is pulling Block B to the right. The tension in the rope is unknown and labeled as T. Assuming the blocks are sliding and on a rough surface with coefficient of kinetic friction μk = 0.4, find the acceleration of the boxes (magnitude and direction) and the magnitude of the tension in the rope. You will need to use Newton's Laws for this problem. Hint: Break the system up and analyze the blocks each with their own FBD/equations. Don't forget the blocks are connected to each other.

A young work crew is trying to quickly finish some touch-up painting to complete a job. Rather than setting up a secure work area, they decide to try a shortcut. Worker A will hold the far end of a 8.00 m work plank that weighs 114 N and is secured with a hinge on the opposite end. Worker B will stand on the plank 4.22 m from worker A. Worker B also brings up his paint can of mass mc = 3.58 kg, which he places 0.430 m from where he is standing on the plank (between the two workers). Worker A needs to supply 483 N of force to keep the end of the plank stable. The acceleration due to gravity is g = 9.81 m/s2. How much WB does worker B weigh? WB = N
