- A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.04 g coins stacked over the 18.2 cm mark, the stick is found to balance at the 41.8 cm mark. What is the mass of the meter stick? Number i Units2. A boy weighting 600 N sits 2.5 m from the center of the see-saw. If his friend weighs 750 N, how far from the center should his friend sit so that the see-saw balances?A uniform meter stick with a mass of 175. grams is placed on a fulcrum. A weight of grams is placed to the right of the fulcrum at a position where the meterstick balances as shown in the diagram. How far must the weight be placed from the fulcrum to balance the meterstick if the fulcrum is located at the 20.0 cm mark? (10.0 cm) I know the answer is 10, not sure how to get it.
- Please show me how to calculate where I need to place the stack of bricks on the right side in order for the beam to become balanced? Please refer to image.The figure shows a 1280 kg car that has slipped over the edge of an embankment. People are trying to hold the car in place by pulling on a horizontal rope. The car's bottom is pivoted on the edge of the embankment, and its center of mass lies farther back, as shown. 2,4m 1,8m 3 If the car makes a 34 degree angle with the horizontal, what force must the people apply to hold it in place? T=_NA 71-kg man stands on his toes by exerting an upward force through the Achilles tendon, as shown in the figure. (Image attached) What is the force in newtons in the Achilles tendon if he stands on one foot? Calculate the force in newtons at the pivot of the simplified lever system shown—that force is representative of forces in the ankle joint.
- When just a single force is present, can an item be in equilibrium? Explain.4. A meter stick has a pivot that is located at (35 cm). On this meter stick weplace 200 g @ 20 cm, 200 g @ 25 cm, 350 g @70 cm and 100 g @80 cm.The meter stick has a mass of 150 g. a. How much mass needs to be placed at 55 cm in order to balance themeter stick.__________________________ b. Where will you put 500 g in order to balance the meterstick?___________________________________ If you could clearly circle the answers I need, that would be great!
