A stone is tied to a string (length = 0.880 m) and whirled in a circle at the same constant speed in two different ways. First, the circle is horizontal and the string is nearly parallel to the ground. Next, the circle is vertical. In the vertical case the maximum tension in the string is 14.0% larger than the tension that exists when the circle is horizontal. Determine the speed of the stone.

A stone of mass 500g is attached to a string of length 50 cm which will break if the tension exceed 20N. The stone is whirled in a vertical circle. The angular speed is slowly increased until the string breaks. Draw a diagram to show the forces acting on the stone in a vertical circle when it is at its higest and lowest points. By suggesting a reason for your answer, state in what position along the vertical circular path...

1. An object of mass 1.2 kg is attached to a string of 0.83 m. When this object is rotated around a horizontal circle, it completes 15 revolutions in 9.6 seconds. a. What is the period (T) of this motion? b. What is the tangential velocity of the object? c. What is the tension on the string? Hint: The tension on the string is the centripetal force that causes the circular motion.

A model airplane of mass 0.4 kg is attached to a horizontal string and flies in a horizontal circle of radius 5.9 m, making 2 revolutions every 7 s. (The weight of the plane is balanced by the upward “lift” force of the air on the wings of the plane.) The accelaration due to the gravity is 9.81 m/s2 . Find the speed of the plane. Answer in units of m/s. Find the tension in the string. Answer in units...

Two masses are tied together with a string and swung at a constant speed in a horizontal circle.   The inner string (connecting the center to the first mass) has a length of 72.0 cm and the outer string (connecting the first mass to the second mass) has a length of 45.0 cm. The inner object has a mass of m1= 540 g, the outer object has a mass of m2=360 g. The balls complete 5 rotations in 6.4 s.   Find...

A 2 kg mass is tied to a string and is being swung in a horizontal circle. The mass has a constant angular velocity of 0.4 rad/s. The string has a Young’s modulus of 10 X 106 N/m2, and the string’s original length is 0.7 m long. The radius of the string is 0.05 cm. How much does the string stretch? You can think of the string as being shaped like a long, thin cylinder. Group of answer choices 5.6...

A mass of 3 kg is connected to a string of length 3.4 meters to form a yo-yo. It is swung in a vertical circle. The string breaks when the tension in the string is 89 Newtons. It happens to reach this tension on the side of the circle (halfway between the top and bottom) and the mass moves through midair at the velocity it was moving at the side when the string broke. What is the maximum vertical displacement...
