An object travels in a circular path of radius 5.0 meters at a uniform speed of 10. meters per second. What is the magnitude of the object's centripetal acceleration?
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
