6. You are not on earth. You have a ball on a string. You whirl it in a vertical circle (a) Choose values for the following. None of them can be 0. i. The value of gravitational acceleration on this planet (on Earth it would be 9.81m/s2 ) ii. The mass of the ball iii. The length of the string iv. The tension in the string at the top of the circle. (b) Draw the Free Body Diagram of the ball at the top of the circle. (c) Label the origin and axes. (d) Calculate the velocity of the ball at the top of the circle. (e) Draw the Free Body Diagram of the ball at the bottom of the circle. (f) Label the origin and axes. (g) If you maintain the same velocity at the bottom as in the top, what is the tension at the bottom?
