Estimate the force a person must exert on a string attached to a0.170 kg ball to make the ball revolve in a circle when the lengthof the string is 0.600 m. The ball makes 1.60 revolutions persecond. Do not ignore the weight of the ball. In particular, findthe magnitude of FT, and the angle ? it makes with the horizontal.[Hint: Set the horizontal component of FT equal to maR; also, sincethere is no vertical motion, what can you say about the verticalcomponent of FT?]

FT = ? N

? = ?Â°

Please include formulas and explanations.
