A 0.087 kg remote control 16.7 cm long rests on a table, as shown in the figure below, with a length L overhanging its edge. To operate the power button on this remote requires a force of 0.470 N Assume the mass of the remote is distributed uniformly, and that the power button is on the end of the remote overhanging the table. a.) How far can the remote control extend beyond the edge of the table and still not tip over when you press the power button? cm b.) How large is the normal force when the button is pressed? N (How would this answer change if the remote were not at maximum extension?)

In exercise physiology studies, it is sometimes important to determine the location of a person's center of gravity. This can be done with the arrangement shown in the figure below. 2.00 m A light plank rests on two scales that read F = 380 N and F = 280 N. The scales are separated by a distance of 2.00 m. How far from the woman's feet is her center of gravity? Need Help? Read It

Two children of mass 21 kg and 26 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 2 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? m

Question on attached image.  In the drawing to the right, a 90.0 cm long metal bar having a mass of 0.500 kg is supported by two strings as shown.  a) Determine the value of the tension in each string.  b) Calculate the position of the center of mass from the left end of the torque bar.

A horizontal 4.0 m long 5.0 N uniform bar at one end is attached to a wall by a frictionless hinge; and at the middle of the bar there is a vertical cable pulling down 7.0 N, and at the middle of the bar there is also a cable that is at 45 ° to the horizontal pulling up as shown. ii) What is the magnitude of the horizontal component of the force on the bar due to the hinge?

Item 3 Hide Timer 01: 3 of 2 You are pushing an 80.0 N wheelbarrow as shown in (Figure 1). You lift upward on the handle of the wheelbarrow so that the only point of contact between the wheelbarrow and the ground is at the front wheel. Assume the distances are as shown in the figure, where 0.50 m is the horizontal distance from the center of the wheel to the center of gravity of the wheelbarrow. The center gravity of the dirt in the wheelbarrow is assumed to also be a horizontal distance of 0.50 m from the center of the wheel. Suppose that the maximum total upward force that you can apply to the wheelbarrow handles is 75 lb. Cons Part A If you apply this estimated force, what is the maximum weight of dirt that you can carry in the wheelbarrow? Express your answer in pounds. w = 6.42 lb Submit Previous Answers Completed Part B If the dirt has the weight you calculated in part A, what upward force does the ground apply to the wheel of the wheelbarrow?

In exercise physiology studies, it is sometimes important to determine the location of a person's center of gravity. This can be done with the arrangement shown in the figure below. -2.00 m A light plank rests on two scales that read F 91 = 440 N and F 92 = 320 N. The scales are separated by a distance of 2.00 m. How far from the woman's feet is her center of gravity? m
