Two wires are tied to the 400 g sphere shown in figure. The sphere revolves in a horizontal circle at a constant speed of 7.60 m/s. (Figure 1) What is the tension in the upper wire? Express your answer with the appropriate units. What is the tension in the lower wire? Express your answer with the appropriate units.
Two cables are attached to the 300g sphere. The sphere
rotates in a horizontal circle at a constant speed of 7.5m / s
a) What is the tension in each of the cables?
b) how many revolutions per minute (rpm) does the
system give?
c) calculate the (rpm) with which the lower cord loses
all its tension

Two wires are tied to the 300 g sphereshown in Figure CP7.61. The sphere revolves in a horizontalcircle at a constant speed of 9.0 m/s.What is the tension in each ofthe wires?T1 = N (top wire)T2 = N (bottom wire)
Two wires are tied to the 400g sphere shown in figure. The sphere revolves in a horizontal circle at a constant speed of 8.40m/s. (Figure 1) What is the tension in the upper wire? What is the tension in the lower wire?
Problem #1 1.5 m The figure shows two wires that are tied to a 0.5 kg mass that revolves in a horizontal circle at a constant speed of 7 m/s. 1.1 m 1.5 m (note that the triangle is NOT equilaterall Find angles first.) Find: (a) the magnitude of the tension of the upper wire (in N); (b) the magnitude of the tension of the lower wire (in N);

2. (5 points) Two rigid wires are connected to the 2.0 kg sphere shown in the figure at right. The sphere revolves in a horizontal circle at constant speed. The distance between the ball and the axle to which the wires are connected is r = 0.866 m (which you could determine using geometrical arguments). 1.0 m (a) For what tangential speed will the tension be the same in both wires? (b) If the ball is rotating with the speed...
A small ball of mass m is tied to a string and set rotating with negligible friction in a vertical circle of radius R with earth's gravity g acting. (a) What is the speed of the ball at the top of the circle so that the tension in the string vanishes there? (b) Given this, what is the speed of the ball at the bottom of the circle, and (c) what is the tension in the string at the bottom...
