Homework Statement



A 5.0 kg object revolving around a circular track in a horizontal plane at constant speed. The radius of the track is 20. meters and the centripetal force on the object is 4.0 x 10 exponent 2 Newtons

1) The objects centripetal acceleration is?

2) The objects speed is?

Homework Equations



Ac = Velocity exponent 2 / raidius

how can i find the velocity for the equation?

The Attempt at a Solution



im not sure how to do it yet can someone give me the equations for the problem?
 
Physics news on Phys.org
Since you can consider F = ma, you can find the centripetal acceleration since you already have the value of the force and mass. With that, you should be able to solve for the velocity.
 
oh thanks is the equation the same for objects speed?
 
how can i solve the objects speed?
