TetherballsUse the 3 step plan of course!For each of the following problems, the mass of the tetherball m = 0.27 kg, and the length of the rope is L = 2.0 m. (Assume the tetherball is small compared with L.) You set up a tetherball in deep space. Find the tension FT in the rope if the speed of the tetherball is v = 3.8 m/s. 48260030903mL00mLYou are still in deep space. Assume the ball takes a period of time T = 0.25 s to complete an orbit. Use the fact that the circumference of a circle is 2πR. Sketch it!Find the speed v of the ball. (Algebra only.)Find the tension FT algebraically first in terms of m, L, T and any necessary constants.Find FT numerically.Aylin’s Challenge Problem: This side view shows the tetherball on Earth, travelling in a circle with speed v = 4.79 m/s (the mass and rope length are the same as before.) The rope make an angle θ = 35o from the horizontal. Find the tension FT algebraically first in terms of the m, L, v, θ, and any necessary constants.102969481832mθL00mθLFind FT numerically. ................
