- A 13.6 kg. 3.6 m long seesaw bar (assume that the bar is uniform) is perfectly balanced upon a support that is 0.2 m to the left of its center. There is a 6.5 kg block sitting on the far right side of the seesaw. How large of a mass do we need to place on the far left of the seesaw for it to be balanced?Two children with masses of 24 kg and 34 kg are sitting on a balanced seesaw. If the heavier child is sitting O.8 m from the center, at what distance from the center is the lighter child sitting? Your answerA 100 kg man balances a boy with mass of 25 kg on a teeter-totter,If the man is at 2 meters from the fulcrum. The boy's distance from the fulcrum is 12 m 16 m 4 m 8 m
- Bart ( whose mass is 31.1 kg) and Milhouse (whose mass is 20.4 kg) sit balanced on a teeter -totter that has its pivot point at its exact center . If the two boys are separated by a distance of 2.52 m, at what distance (in m) from the pivot point must Milhouse be sitting at in order to maintain the balance? Explain how you solved the problem involving children balancing on a teeter-totter. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!Two pants of a balance are 26.6 cm apart the fulcrum of the balance has been shifted 0.752 cm away from the center by a dishonest shopkeeper. by what percentage is the true weight of the goods being marked up by the shopkeeper? Assume the balance has negligible mass. answer in units of percentageTwo 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
- Two kids are on a uniform seesaw supported at its center. The kid is on the right side of the seesaw has a mass m kg and is at a distance 1.59 from the center of the seesaw. The kid is on the left side of the seesaw has a mass 30.8 kg and is at a distance 1.49 from the center of the seesaw. The seesaw is in static equilibrium. What is the mass m in kg? Give your answer to three significant figures.A box of mass 5 ?? is placed 1.5 ? at the end of a plank pivoted in the middle. Anotherbox of mass 15 ?? is placed somewhere to balance the system.a. Find the weight of the two crates. [4 marks]b. Find the location of the other box in the balanced system. [3 marks]c. The first box is replaced with a box of weight 17 0 ? at 0.7 ? from the pivot.What is the new location of box two to balance the system?A 50 N weight is located 20 cm from the fulcrum of a balance beam. At what distance from the fulcrum should a 20 N weight be placed to balance the system?
- A rider of mass 77.0-kg sits 1.60 meters left of the pivot point. A different rider sits 3.3 meters to the right of the pivot point. If the see-saw is in equilibrium, what is the rider on the right's mass? The mass of the see-saw is 18.9-kg Give your answer in kilograms to 3 significant figures (1 decimal place).A rider of mass 78.0-kg sits 1.70 meters left of the pivot point. A different rider sits 3.5 meters to the right of the pivot point. If the see-saw is in equilibrium, what is the rider on the right's mass? The mass of the see-saw is 19.2-kg Give your answer in kilograms to the correct number of significant figures.Bob and Anna sit on opposite ends of a uniform see-saw which is 12.0 m in length. The see-saw is balanced by a fulcrum which is located 4.00 m from Bob. Bob has a mass of 85.0 kg, and the see-saw itself has a mass of 100 kg. Anna’s mass is unknown. NOTE THAT THE FULCRUM IS NOT PLACED AT THE CENTER OF MASS OF THE SEESAW!!! a) What is the net torque on the see-saw? Explain clearly and briefly how you know. b) Draw a properly labeled extended force diagram of the see-saw. c) Solve for Anna’s mass.
