A rock is tied to a string and spun in a circle of radius 1.4 m as shown in the figure below. The speed of the rock is 13 m/s.

(c) What is the total force on the rock directed toward the center of its circular path? Express your answer in terms of the (unknown) tension T in the string. (Use the following as necessary: ?.) F = (d) Apply Newton's second law along both the vertical and the horizontal direction and find the angle ? the string makes with the horizontal. (Assume a coordinate system in which the positive x direction is horizontally to the right and positive y direction is vertically up.) ? = ° counterclockwise from the +x-axis

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 300g rock tied to a string is rotated in a vertical circle (up and down, so gravity is important) with radius 0.5m. Model the rock as a point particle. If a torque of 2Nm is applied for 3s, what is the rotation rate of the rock? What is the tension in the string at the top of the circle?

A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.154 kg and moves at v = 5.16 m/s. The circular path has a radius of R = 1.01 m 1) What is the magnitude of the tension in the string when the ball is at the bottom of the circle? 2) What is the magnitude of the tension in the string when the...

A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.15 kg and moves at v = 4.89 m/s. The circular path has a radius of R = 0.94 m What is the minimum velocity so the string will not go slack as the ball moves around the circle?
A ball of mass m is tied to a string and is rotating in a vertical...
A ball of mass m is tied to a string and is rotating in a vertical plane. The string is elastic (it stretches), which causes the path to be elongated vertically rather than perfectly circular. At the top of the path, the speed has the minimum value that still allows the ball to complete its circular path. Find: the length of the string when it makes an angle θ with respect to the horizontal. The following quantities are known: Mass...

Kim whirls a 10 kg bag, which is connected to a string in a horizontal circle above her head at some unknown constant speed v. Suddenly, the string breaks and the bag flies off and lands 10 m away with a time of flight of 0.5 s. If the string was 1.5 m long, a) What was the speed of the rock before the string snapped? (vertical motion irrelevant) b) Find the tension in the string before it snaps.

A ball on the end of a string is whirled around in a horizontal circle of radius 0.340 m. The plane of the circle is 1.50 m above the ground. The string breaks and the ball lands 1.50 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion. Magnitude m/s2Direction away from the center of curvature toward the center of curvature

1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...

A 1.50-m string of weight 0.0125 N is tied to the ceiling at its upper end, and the lower end supports a weight ?. (Ignore the very small variation in tension along the length of the string that is produced by the weight of the string.) When you pluck the string slightly, you notice that the waves traveling up the string have amplitude 8.00 mm, wavelength 0.040 m and speed 12.0 m/s. Assuming that up is the positive direction, which...

A small 0.441-kg object moves on a frictionless horizontal table in a circular path of radius 2.26 m, see image below. The angular speed is 7.09 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins to pull the string downward to make the circle smaller. If the string will tolerate a tension of no more than 1350 N,...
