A 2 kg hangs from the bottom of a 40 cm string fixed at its top end to the ceiling. The mass is then set to move in a horizontal circle at 2m/s under the action of gravity and the tension of the string only. Determine the angle made between the string and the vertical. b) the same mass and string are configured so that the mass can move in a vertical circle, again under the influence of gravity and tension only. If the tension of the string is 40N at point A, determine the tension at the bottom.

A 0.104 kg meter stick is supported at its 40 cm mark by a string attached to the ceiling. A 0.644 kg object hangs vertically from the 7.09 cm mark. A second mass is attached at another mark to keep it horizontal and in rotational and translational equilibrium. If the tension in the string attached to the ceiling is 17.4 N, find the value of the second mass. The acceleration due to gravity is 9.8 m/s 2 . Answer in...

A 5.61-kg ball hangs from the top of a vertical pole by a 2.43-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.17 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0° and 90°, that the string makes with the pole. Take g = 9.81 m/s2. What is the tension of the string?

An iron bolt of mess 60.5 g hangs from a string 33.8 cm long. The top end of the string is fixed. Without touching it, a magnet attracts the bolt so that it remains stationary, but is displaced horizontally 28.5 cm to the right from the previously vertical line of the string. Draw a free-body diagram of the bolt. Find the tension of the string. Find the magnetic force on the bolt. magnitude N direction

A block A with a mass of 3 kg rests on a horizontal table top. The coefficient of kinetic friction, μk = 0.5. A horizontal string is attached to A and passes over a massless, frictionless pulley, and block B with mass 2 kg hangs from it. Because of the pull of gravity, the masses accelerate. What is the Tension in the string (in Newtons)?
