Question

a 981 kg test car travels around a circular track with a radius of 0.625 km. if the magnitude of centripetal force is 2433, what is the cars speed? what is the cars centripetal acceleration?
use F=ma, and a=v²/r
where m=981 kg, r=625 m, and F=2433 N (unit not given, Newton assumed).
Solve for v.
