A bird is flying in a circle of radius 50m at a constant speed of 5 m/s. The bird is flying clockwise, as seen from above. at the moment when the bird is flying north, what is the magnitude and direction of the bird's acceleration?

0.5 m/s² clockwise

Explanation:

Acceleration: This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s².

The acceleration of a body undergoing circular motion is given as,

a = v²/r Equation 1

Where a = acceleration of the bird, v= velocity of the bird, r = radius of the circle.

Given: v = 5 m/s, r = 50 m.

substitute into equation 1

a = 5²/50

a = 25/50

a = 0.5 m/s².

Hence the acceleration of the bird = 0.5 m/s² clockwise
