Question description

Answering step by step as showing as much work as possible. A diagram is in the first question in order to help with the understanding. The first two questions have three parts that explain each of the parts that have to be found and solve. Las question ask for a free body or force diagram in order to explain the question.

Two ropes are attached to either side of a 50.0 kg wagon as shown below. The rope on the left is pulled at an angle 35° to the horizontal with a tension of 80.0N and while the rope on the right is pulled directly to the east (0° relative to the horizontal) with a tension of 85.0N. a) Find the components of the tension forces applied by the ropes. Show all work. b) Find the net force in the x (horizontal) direction assuming no friction. Show all work. c) Find the net acceleration of the wagon in the horizontal direction.

The coefficient of static friction is µ s = 0.60, and the coefficient of kinetic friction is µk = 0.35. A horizontal force, F, is applied to the block. As F is increased, the block begins moving. a) Find the minimum force, F, required for the block to just start to move. b) Find the force, F, required for the block to continue to move at a constant velocity. c) Explain what happens to the motion of the block if a force is applied greater than those found above. Answer: (8 points) 3. A 3.0 x 104 kg steel beam is lifted by a large crane. The beam accelerates upward at 1.50 m/s2. Find the applied force. Show all your work including a free body (or force) diagram. Answer: © 2009 K12 Inc. All rights reserved. Revised 2018dg Copying or distributing without K12’s written consent is prohibited.

Only issue was the guy's response time which was a bit long, which made me a bit anxious. Reached out to the help desk and they helped me out, turns out the tutors aren't all from US which meant there was a time difference. No issues on the quality.
