Steve is whirling a rubber cork, tied with a string to his finger, over his head as shown in the figure. the motion of the cork is similar to the motion of a planet in the solar system around the sun. which force in the solar system is similar to the tension in the string?
a) nuclear force
b) magnetic force
c) gravitational force
d) electrostatic force

Gravitational force because the gravist of when your swinging it is like the sun pulling the planets in

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.

B. elliptical. as in oval. 0 (==
