3 Students and a Textbook-Extended +X students converge on the last textbook in the store. All three grab it and begin to pull in the directions shown in the above figure. Student A exerts a force of 55.46 N, student B puils with a force of 17.30 N, and student C pulls with a force of 59.33 N at an angle 6(theta)-72.61 degrees above the -x axis.

Three ropes are tied in a knot as shown in the figure. One student pulls on rope A with 1.0 pound of force, and another student pulls on rope B with 7.0 pounds of force. How hard and in what direction must you pull on rope C to balance the first two pulls? Give the direction by specifying the angle (clockwise or counterclockwise) of the pull with the direction of rope A. 1. Rope B 2. Find the magnitude and...

Assignment Score: 92% Resources Give Up? Feedback Try Again Question 9 of 17 Attempt 3 Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 71.3 N , Jill pulls with 94.1 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 143 N . (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find...

Three forces in the x-y plane act on a 3.70 kg mass: 16.70 N directed at 50o, 11.20 N directed at 168o, and 4.40 N directed at 233o. All angles are measured from the positive x-axis, with positive angles in the Counter-Clockwise direction. Calculate the magnitude of the acceleration. Calculate the direction of the resultant force using the same sign convention as above (in degrees).

1.If there were a set-up with three vectors all lying in the rst quadrant, in which quadrant must the equilibrant be? Why? 2.What sources of error could exist to account for differences between the standard values and the graphical and experimental results? 3.The direction of the vector (the angle) was always measured counter clockwise from the positive x axis. If the angle were instead measured clockwise from the positive y-axis, how would that effect the way we determine the x-...

61. Three rugby players are pulling horizontally on es attached to a box, which remains stationary. Player 1 exerts a force F1 equal to 100 N at an angle 01 equal to 60° with respect to the +x direction (Figure 4-39). Player 2 exerts a force F2 equal to 200 N at an angle 02 equal to 37° with respect to the +x direction. The view in the figure is from above. Ignore friction and note that gravity plays no...

You see there that depending on the angle of “pull", e, three different motions can occur - the spool either rolls toward or away from the person pulling the cord or, at a critical angle of pull, does not rotate. The purpose of this exercise is to analyze this behavior using fundamental principles of mechanics. The physical system is shown in the figure and consists of two concentric spools of radius R, and R,, respectively. Cord is wrapped around the...
