(adsbygoogle = window.adsbygoogle || []).push({}); centripetal force (urgent)

1. The problem statement, all variables and given/known data

what should a centripetal force vs. velocity(speed) graph look like.

what should a velocity(speed) vs. radius(of the circle) look like.

what should a velocity(speed) vs. stopper mass graph look like.

2. Relevant equations

To find centripetal force, i mulitiplied the mass of the string by 9.80m/s^2

To find velocity, i divided the circumference by the period

The centripetal force in the first trial was (.1 kg)*9.80, second trial was (.2 kg)*9.80, third trial was (.3 kg)*9.80, the fourth trial (.4 kg)*9.80

3. The attempt at a solution

i am supposed to use pwreq for the first graph and pwrReg for the other two on my TI 84 to get the shape but they don't seem right.

For me, the first one was an upside down parabola, the second and third a straight line

Thank you for the help
