Explain why a point on the rim of a tire has an acceleration when the tire is on a car that is moving at a constant linear velocity.

Respuesta :

Answer:

Explanation:

This is because even with the constant linear velocity,  as that point transverses the circle its direction  is always changing, and any point on a rotating object possesses centripetal acceleration. hence it is said to be accelerating. Also we can see that from the formula for centripetal acceleration (a) = [tex]\frac{velocity^{2} }{radius}[/tex] ,  we can have acceleration with just velocity.
