A 200 g ball moves in a vertical circle on the end of a 50 cm long string, with no additional input of energy. If its speed at the bottom is 10 m s-1, calculate: The velocity at the top of the circle The tension at the top of the circle
The ball shown in the diagram is attached to a rotating pole with two strings. The ball has a mass of 0.250 kg and rotates in a horizontal circle at a speed of 8.0 ms 1. Determine the tension in each string.
Hi, I can't get the correct draft number from following question. I get 0.5195m. Weight of bouy + weight of mooring lines = bouyancy of bouy... Am I wrong? A CALM buoy is moored in 30m water depth using a 6 line configuration. The CALM buoy is cylindrical with a diameter of 5m and…
A water pipe having a 5 cm inside diameter carries water into the basement of a house. If the pipe tapers to 2.5 cm, rises to the second floor 7.6 m above the input point and then flows out into the atmosphere at a speed of 12.4 m/s. a) What volume of water flows into the atmosphere during a…
