A meter stick is supported by a knife-edge at the 50-cm mark. If you hangs masses of 0.50 kg and 0.75 kg from the 25-cm and 80-cm marks, respectively. Where should you hang a third mass of 0.25 kg to keep the stick balanced?

the third mass should be placed at x3=0.1m=10cm from the left to keep the stick balanced.

The center of gravity of the meter stick is 49 cm. mass of meter stick 50 g . mass of hanger #1 =5 g. mass of hanger #2 = 5 g. 1.Place the fulcrum at 51 cm. Attach a 200 g mass, plus hanger #1, at 17 cm on the meter stick and calculate where to attach a 200 g mass, plus hanger #2, to balance it. 2.Balance the stick with the fulcrum at its center of gravity. Attach a...

A meter stick on a horizontal frictionless table top is pivoted at the 80-cm mark. A force F1 = 5 N is applied perpendicularly to the end of the stick at 0 cm, as shown. A second force F2 (not shown) is applied at the 100-cm end of the stick. The stick does not rotate. a) What is the torque (magnitude and sign) about the pivot from F1? b) Explain why the torque from the pivot about itself is zero....

A meter stick has the pivot placed at the 28 cm mark. A mass of 156 g is placed at the 3 cm mark, and another mass of 94 g is placed at the 61 cm mark. If these masses create equilibrium what is the mass of the meter stick in grams? Round your answer such that it has no decimal.

1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark.

1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark. An unknown mass is placed on the other side of the meter stick and moved until the entire system is balanced. If the unknown mass is placed at the 75.00 cm mark, then what is the value of the unknown mass? Ignore the mass of the knife-edge clamps and assume that...

You attach a meter stick to an oak tree, such that the top of the meter stick is 2.47 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.271 seconds to pass the length of the meter stick, how high above the ground was the acorn before it fell, assuming that the acorn did not run into any branches or leaves on the way down? acorn's height: _______m

The figure shows a meter stick lying on the bottom of a 100-cm-long tank with its zero mark against the left edge. You look into the tank at a 30 angle, with your line of sight just grazing the upper left edge of the tank. a. What mark do you see on the meter stick if the tank is empty? b. What mark do you see on the meter stick if the tank is half full of water? c. What...

A thin stick of length 80.0 cm and mass 120.0 g has two small spherical masses attached to its opposite ends (treat them as point masses). One mass is 20.0 g and the other mass is 50.0 g. The stick rotates frictionlessly about a horizontal axis passing through its centre. If the stick starts from rest in a horizontal position, what is the linear speed of the larger spherical mass at the moment that it is passing through its lowest...
