Answer:
hold on im going to answer the best I can
the Doppler effect. (I don't know how to explain it lol)
Answer:
Average velocity of an object is equal to the instantaneous velocity when it's acceleration is zero.
Explanation:
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:

Here, 
∴ 
Therefore, the acceleration of a point on the wheel is 11.43 m/s² acting radially inward.
