A tennis ball connected to a string is spun counterclockwise around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.16 kg and moves at speed v = 2.4 m/s. The circular path has a radius of R = 0.26 m. The ball is at the bottom of the circle as shown. What is the magnitude of the tension force on the ball at this instant, in Newtons? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
See Conceptual Example 6 to review the concepts involved in this problem. A 10.5-kg monkey is hanging by one arm from a branch and swinging on a vertical circle. As an approximation, assume a radial distance of 90.8 cm is between the branch and the point where the monkey's mass is located. As the monkey swings through the lowest point on the circle, it has a speed of 3.88 m/s. Find (a) the magnitude of the centripetal force acting on the monkey and (b) the magnitude of the tension in the monkey's arm.

Shown is a 100 g puck revolving at 100 rpm on a 20-cm-radius circle on a frictionless table. A string attached to the puck passes through a hole in the middle of the table. The end of the string below the table is then slowly pulled down until the puck is revolving in a 10-cm-radius circle. How many revolutions per minute does the puck make at this new radius?
A 3200 kg coaster car rolls along the frictionless track shown. To safely make it through the loop there is a minimum speed the coaster must have at the top of the loop. At this speed the normal force of the track pushing downward on the coaster is zero. The radius of the circular loop is 14.1 meters. At the top of the loop of radius 14.0 m the force of gravity is the only force acting on the coaster. What is the magnitude of the coaster's acceleration at the top of the loop?
And don't worry about whether the passengers would actually survive the trip. They are lightweight crash test dummies. NTC A cart of mass m= 347 kg is going around a circular loop-the-loop. There is no motor. The cart moves only under the influence of gravity. Ignore friction and let g = 9.81 meters per second squared. The loop has a radius of r meters. When the cart is at the top of the loop, the normal force on the cart (exerted by the track) pushes down on the cart with a force of N = 1,330 newtons. When it is at the bottom of the loop, the cart has a speed of 30.7 meters per second. What is the radius of the loop (in units of meters)?
For the normal force in the drawing to have the same magnitude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Suppose, for example, that the track has a radius of 2.23 m and that the driver goes past point 1 at the bottom with a speed of 24.0 m/s. What speed must she have at point 3, so that the normal force at the top has the same magnitude as it did at the bottom?

A string can support a stationary hanging load of mass 25 kg before breaking. a) Calculate the maximum tension that the string can support. b) Suppose one end of the string is attached to an object of mass m = 3 kg, while the other end is fixed to the center of a frictionless table as shown in the figure. When given an initial speed, the object moves along a horizontal circle of radius R = 0.8 m. Calculate the maximum speed the object can have before the string breaks.
