With dashed lines, draw the vertical and horizontal components of T, and label the angle 6' between T and the vertical. In what direction, horizontal or vertical, does the pig accelerate? What does this tell you about the net vertical force on the pig, and the relationship between mg and TV? Which force in the diagram is the centripetal force? What is the relationship between Th , TV and i9? Write an equation that shows the relationship between va/r to T and 6. Refer to your answer in step 4 and make a substitution in the equation to eliminate TV. Solve the equation for V. Notice that the mass term cancels
