Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N but friction prevents the crate from sliding.
Part A
Draw a free body diagram of the crate in the diagram below. Use the dot as the particle representing the crate and make sure to draw your vectors so that they have the correct orientation and their magnitudes in newtons, are consistent with the conditions of the problem.
Draw the vectors starting at the black dot. The location, orientation, and length of the vectors will be graded.

This is details for Part C: Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N, but friction prevents the crate from sliding. Part C: Now assume that the crate is sliding along the floor with constant velocity. What is the magnitude Fp of the force you need to exert on the crate to make...
Tactics Box 5.1 Working with Friction ForcesLearning Goal:To practice Tactics Box 5.1 Working with friction forces.Although friction is a complicated force, many aspects of it can be described with a simple model. This Tactics Box presents the conditions under which these models are valid and outlines the essential steps in solving friction problems.TACTICS BOX 5.1 Working with friction forces1. If the object is not moving relative to the surface it's in contact with, the friction force is static friction. Draw...
1. You want to move a 500-N crate across a level floor. To start the crate moving, you have to pull with a 230-N horizontal force. Once the crate breaks loose and starts to move, you can keep it moving at constant velocity with only 200 N. What are the coefficients of static and kinetic friction? 2. In the previous example, suppose you move the crate by pulling upward on the rope at an angle of 30.0◦ above the horizontal....
Question 5 15 marks You should be able to answer this question after studying Unit 10 A crate, initially at rest, is pushed along a straight line up a rough ramp that makes an angle of 18° with the horizontal. The magnitude of the pushing force is 33 N, in a direction parallel to and up the ramp, and the acceleration of the crate is 0.16 ms-2. The coefficient of sliding friction between the crate and the ramp is 0.35....
A 3.00-m-long, 140-N, uniform rod at the zoo is held in a horizontal position by two ropes at its ends in (Figure 1). The left rope makes an angle of 150° with the rod and the right rope makes an angle 9 with the horizontal. A 90- N howler monkey (Alouatta seniculus) hangs motionless 0.50 m from the right end of the rod as he carefully. Make a free-body diagram of the rod. Draw the vectors starting at the black dots. The...
You have a crate full of books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to start moving? (b) Once...
