the string tension is the hypotenuse of a force triangle formed by
... the tension , the weight of the ball , and the centripetal force
the centripetal force equals ... m g / tan(14ยบ) ... equals ... m v^2 / r
tension^2 = weight^2 + centripetal force^2
a 1.45 kg ball is suspended from a 0.80m string and swung in a horizontal circle at a constant speed such that the string makes an angle of 14 degrees with the vertical.
what is the tension in the spring
what is the speed of the ball.
