Answer:
The acceleration of a point on the wheel is 11.43 m/s² acting radially inward.
Explanation:
The centripetal acceleration acts on a body when it is performing a circular motion.
Here, a point on the bicycle is performing circular motion as the rotation of the wheel produces a circular motion.
The centripetal acceleration of a point moving with a velocity and at a distance of from the axis of rotation is given as:
a = v2/r
Here, V = 8m/ s,r = 0.70 m
∴ a = 8/0.70 = 11.43m/ s2
Therefore, the acceleration of a point on the wheel is 11.43 m/s² acting radially inward.
