Imagine a meter stick set up as in the figure (in the video above). It hangs from a central bracket, and two hanging masses can hang from it from each of their brackets. At a third location, a force probe can either pull up or pull down on the stick, depending on what is needed to balance the stick. The mass of the meter stick is 120 g. sketch the situation (drawing r1, r2, r3, F1, F2, and F3) and determine the magnitude (value) and direction (+ or -) of each torque. Remember that the x value given in the table is the position of the hanging mass, but that might be different from the r value you need to use. Don't include the mass of a bracket that would hold the hanging mass in place; assume the mass listed is the entire mass hanging at that point.

Fill in the data as you complete the lab. In the table, m represents mass and r represents the distance from the fulcrum. Use a zero or a dash (–) when there is no second object on one side of a problem. Include units with all data. The image of the balancing act is scenario 4.
Three blocks are connected as shown in the diagram above. Block A has a mass of 1.1 kg and hangs from a (massless) string that runs over a (massless and frictionless) pulley. The other end of the string is connected to Block B which has a mass of 3.5 kg. The other side of Block B is connected to a (massless) string that runs over a (massless and frictionless) pulley and then connects to the hanging Block C which has a mass of 1.7 kg. Block B is sliding down an (essentially frictionless) plane that is inclined at an angle of θ = 23 degrees from the horizontal, as shown. All of the blocks move together when they are released from rest. Block B slides down and to the right. What is the speed of Block B (in units of meters per second) after it has slid a distance d2 = 0.23 meters, starting from rest?

Could you please answer the question in the image and this one below that follows the image. Question 5. The situation for this problem is as explained in question 4. Block E is moving up and to the left (and Block D is moving down). The mass of Block D is 3.8 kg. The mass of Block E is 2.9 kg. The coefficient of kinetic friction between Block E and the plane is 0.42. The inclined plane is inclined at an angle of θ = 24 degrees above horizontal. Calculate the acceleration of Block E (in units of meters per second squared). For the purpose of this question, the acceleration is positive it points up and to the left (it is negative if it points down and to the right).
In the figure at the right is shown three graphs of the shapes of the same taut elastic string in three different circumstances, labeled A, B, and C. In some of the problems below, the string represents a guitar string, tied down at both ends, while in others, it is part of a very long telephone wire whose ends are not shown. Be careful to note which is which for each problem! The string is light enough that the effects of gravity can be ignored. In each case, the bit of string at the position x = 23 cm is painted blue.1. Suppose the three graphs all represent the same string, tied down at x = 0 and x = 70 cm, and at the same tension. What can you say about the three frequencies of oscillation? a. Situation A has the highest frequency. b. Situation B has the highest frequency. c. Situation C has the highest frequency. d. The three frequencies are all the same. e.

webassign.net/web/Student/Assignment-Responses/last?dep=29184236 RE You set up a Halloween prank by attaching a small board to a hinge above your front door. The far end of the board is held up by a cable that can be released by remote control. You place a spooky spider on the board that is dropped on unsuspecting trick-or-treaters when you release the cable. The drawing below shows the set-up. *Paused V 40° Hinge 60 cm You use a board that is 60 cm long and the cable makes an angle of 40 degrees with the board when the board is held horizontally. You place the spider a distance of r = 29 cm from the hinge. The board has a mass of 3.0 kg and the spider has à mass of 1.2 kg. The hinge applies both a horizontal force.and a vertical force. You will be asked to determine the direction of both of these forces (left, right, up, down). What is the magnitude of the tension in the cable in Newtons? T = 25.92 XN What is the magnitude and direction of the horizontal force from the hinge? Enter a…
