biomechanics problem 1. A see-saw on a playground has a 45kg child sitting 2.5m from its fulcrum. a. His dog has a mass of 30kg. How far does the dog need to sit away from the fulcrum on the opposite side of the see-saw to make it balance? b. The dog's three 5kg puppies join her on the see-saw. How far from the fulcrum does the group need to move for the see-saw to continue balancing?
there are two children playing on a playground seesaw. one child has a mass of 25 kg the child sits on one end of the long uniform beam which has a mass of 20 kg. and another 45 kg child sits on the other end., the seesaw balances when a fulcrum is placed below the beam a distance of 1.50 m from the 25 kg-child, how long is the beam?
Problem 10: A small child with mass m is sitting on a see-saw a distance L from the pivot Key Concepts: Torque, Rotational Dynamics a) Where should you sit to balance the see-saw if you are 4 times heavier than the child, i.e. find Explain your reasoning in Fig. 6 b) What is the force exerted on the see-saw by the fulcrum? Find its magnitude and direction M FIG. 6
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?

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...
Name: PHYSICS 1111 armUp for 07 March are sitting on opposite sides of a see-saw at positions of 3 m from the son on the right has a fulcrum. The le the left has a mass of 50 kg and the person on the nght has a mass of 80 k person on a What is the net torque on the see-saw? b. Where would a 40 kg person have to sit on the see-saw in order to balance it?
Two children are balanced on a seesaw of negligible mass. The first child has a mass of 26 kg and sits 5m from the pivot. If the second child has a mass of 30kg, how far is she from the pivot?
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?
QUESTION 27 Cathy (m3) James (mi) D Emily (m2) L2 L/2 A see-saw is made by pivoting a uniform board of length L = 4.64 m at its center. James has a mass m of 52.4 kg and sits at the left end, and Emily has a mass m2 of 32.4 kg and sits at the right end. What distance to the right of the pivot should her sister Cathy, whose mass mz is 19kg, sit in order for the...
Need help with part C. Thank you! This is the figure above. However, it has different values than the homework question above. PRACTICE IT Use the worked example above to help you solve this problem. A woman of mass m = 53.6 kg sits on the left end of a seesaw-a plank of length L = 4.39 m, pivoted in the middle as shown in the figure. (a) First compute the torques on the seesaw about an axis that passes...
