Object's centripetal acceleration is 20 m/s^2
An object moving in a circular path with a constant speed, does have an acceleration, as it changes its direction as the object rotates. This centripetal acceleration can be found using below mentioned relation:
Ac(centripetal acceleration) = (v^2)/r; where, v is the constant speed of object and r is the radius of circular motion
Therefore, Ac = 10*10/5 = 20 m/s2
