A 5.4 kgkg cat and a 2.5 kgkg bowl of tuna fish are at opposite ends of the 4.0-mm-long seesaw. How far to the left of the pivot must a 3.8 kgkg cat stand to keep the seesaw balanced?

The center of gravity of Kelly's outstretched arm is located 21 cm from the axis of rotation in her shoulder. Her arm has a mass of 4.2 kg and is 56 cm long. Assuming the deltoid's force is horizontal, what is the magnitude of the force her deltoid muscle must exert on Kelly's upper arm so she can hold a 6.0 kg mass stationary 15 degree above the horizontal as shown? Her deltoid muscle attaches to her upper arm at a point 18 cm from her shoulder joint. 6 kg 15° 21 cm Fdeltiod

While on a camping trip, a man would like to carry water from the lake to his campsite. He fills two, non-identical buckets with water and attaches them to a 1.51 m long rod. Since the buckets are not identical, he finds that the rod balances about a point located at a length I 0.0367 m from its midpoint, as shown. The weight of the rod and empty buckets is negligible compared to the weight of the water, and the buckets are not shown to scale. Which bucket holds more water? bucket 2 1 bucket 1 They hold the same amount of water. How much more water does the heavier bucket contain, expressed as a percentage? percentage:

To get up on the roof, a person (mass 87.0 kg) places a 5.60 m aluminum ladder (mass 14.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2 m from the bottom. The person is standing 3 m from the bottom. What are the magnitudes (in N) of the forces on the ladder at the top and bottom? top N bottom N

The meterstick shown is 100 cm long. It is free to pivot around its center of gravity (CG), which is at the 50 cm 10 20 30 40 50 60 70 80 90 mark. There is a 20.0 N block hanging from the 80 cm mark. Decide where each of the other blocks should be placed, one at a time, to balance out the 20.0 N block. 3 2 1 At what mark on the meter stick would you place a 19.0 N block to balance the 20.0 N block? mark: cm At what mark on the meter stick would you place a 42.0 N block to balance the 20.0 N block? mark: cm about us careers privacy policy terms of use contact us help -8

Rylie, whose mass is 73.3 kg, is standing on the edge of a steel beam that overhangs a construction site. The horizontal beam is 5.98 m long and has a mass of 128 kg. The distance between the two posts is 3.71 m.

A small airplane is sitting at rest on the ground. Its center of gravity is 2.58 m behind the nose of the airplane, the front wheel (nose wheel) is 0.800 m behind the nose, and the main wheels are 3.02 m behind the nose. What percentage of the airplane’s weight is supported by the nose wheel, and what percentage is supported by the main wheels?

A 1.90-m-long barbell has a 24.0 kg weight on its left end and a 32.0 kg weight on its right end. Where is the center of gravity if the 9.00 kg mass of the barbell itself is taken into account?
