Find Centrifugal Force

mathxyz · 2024-03-06 05:24:18

The centrifugal force of an object moving in a circle varies jointly with the radius of the circular path and the mass of the object and inversely as the square of the time it takes to move about one full circle. A 6-gram object moving in a circle with a radius of 75 centimeters at a rate of 1 revolution every 3 seconds has a centrifugal force of 5,000 dynes. Find the centrifugal force of a 14-gram object moving in a circle with radius 125 centimeters at a rate of 1 revolution every 2 seconds.

F = centrifugal force

K = constant of proportionality

r = radius of circular path

m = mass

t = time (in seconds)

Before answering the question, let me know if my equation is correct.

F = (rkm)/(t^2)

If the equation is correct, I will take it from here.

The trick is to set up the correct equation leading to the right answer. There are lots of word problems that are simply not easy to do so.

Thanks. Math can be fun when understood.
