A 0.12 kg ball is attached to the end of a string. It is swung in a vertical circle of radius 0.24 m. At the top of the circle its velocity is 3.2 m/s. a). Write an equation needed to determine the tension (FT) in the string.

b). Solve those equations for the tension (FT) in the string. (answer & units)

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

Iwould think it is temperature, silica, oxides (gases)
