For an object traveling with uniform speed along a circular path, the centripetal force is F = mv^2 / r, where m is mass, v is velocity, and r is radius. You've been given F, m, and v, so r is your only unknown. Solve algebraically.

Centripetal force = mV²/r
m is mass
V is velocity
r is radius
6000 = 1200(20)²/r
6000r=1200(400)
6000r=480000
r=80 m
Answer is b. 80 m

F = mv^2 / r So for this problem, F = 2000(25^2) / 80
