Answer:
Explanation:
At the point when an object moves in a circle, it has a centripetal acceleration, coordinated toward the center. We realize that centripetal acceleration(ac) is given by ac=v^2/r. This centripetal acceleration is coordinated along a radius so it might likewise be known as the radial acceleration.
On the off chance that the speed isn't consistent, at that point there is additionally a tangential acceleration (at). The tangential acceleration is, in fact, tangent to the path of the object's movement.
The velocity of the particle must be tangential.
Now,
tan 30° =
