child a o child a Two children are balanced on a seesaw of mass 11.0 kg. The first child has a mass of 26.0 kg and sits 1.60 m away from the pivot. The center of mass of the seesaw is 0.113 m from the pivot. (a) How far from the pivot does the second child sit if he has a mass of 31.0 kg? (b) What is the supporting force exerted by the pivot? LPivot center of mass
The two children are balanced on a seesaw of negligible mass (this assumption is made to keep the example simple). The first child is 26.0 kg and sits .160 m to the left of the pivot. The seesaw has a mass of 12 kg. If the second child is 32.0 kg, how far is she from the pivot? What is the supporting force exerted by the pivot?
3. Two children are playing on a seesaw of negligible mass. The first child has a mass of 20.0 kg and sits 1.2 m from the pivot. (i) If the second child has a mass of 30.0 kg, how far is she from the pivot? (ii) What is the supporting force exerted by the pivot? 4. (a) Three point masses are attached to a massless rigid rod. Mass mi- 1.0 kg is located at x 1.0 cm, mass m 2.0...
Question Part Points Submissions Used Two kids create a makeshift seesaw by setting a 4-m long uniform plank on a saw horse. The saw horse is 0.5 m to the left of the center of mass of the plank. The child of mass m1 = 42 kg sits at the left end of the plank. The child of mass m2 = 31 kg sits 1 m to the right of the center of mass of the plank. What is the...
Suppose two children are using a uniform seesaw that is 3.00 m long and has its center of mass over the pivot. The first child has a mass of 30.0 kg and sits 1.40 m from the pivot. (a) Calculate where the second 18.0 kg child must sit to balance the seesaw. (b) What is unreasonable about the result? (c) Which premise is unreasonable, or which premises are inconsistent? Please show work and explanations.
Two kids create a makeshift seesaw by setting a 4-m long uniform plank on a saw horse. The saw horse is 0.5 m to the left of the center of mass of the plank. The child of mass m1 = 48 kg sits at the left end of the plank. The child of mass m2 = 35 kg sits 1 m to the right of the center of mass of the plank. What is the mass of the plank?
Two children of mass 18 kg and 29 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 5 m, at what distance from the pivot point is the small child sitting in order to maintain the balance?
A seesaw consisting of a uniform board of mass and length supports at rest a father and daughter with masses my and respectively, as shown in the figure. The support (called the futrum) is under the center of gravity of the board, the father is a distance from the center, and the daughter is a distance from the center A balanced system ME (a) Determine the magnitude of the upward forcen exerted by the support on the board SOLUTION Conceptualize...
dltión of equilibrium equith from t fros 4.0 kg serves a seesaw for two children. A child of mass 38 kg sits shdition for tTh saw is balanced (in equilibrium). A) Write the rotational child on the lefts acting on the seesaw (with torques included), b) calculate on the right m ren end 1.5 frof mass 0ke uibi he pim from the pivot point. The other child sits on the left end of the seesaw condition for the torques acting...
I need help with exercise and practice it. PRACTICE IT Use the worked example above to help you solve this problem. m 56.3 kg sits on the left end of a seesaw A woman of mass -a plank of length L 4.68 m, pivoted in the middle as shown in the figure (a) First compute the torques on the seesaw about an axis that passes through the pivot point. Where should a man of mass M = 74.9 kg sit...
