Question

Calculate the centripetal acceleration, ac, of various objects. Yelena is driving her car on a dry, non-slippery road. The car moves forward with a speed of 26.7 m/s. What is the centripetal acceleration of the tire which has a radius of 0.55 m?

Arek is riding his bicycle on a non-slippery bike path. The wheel has a radius of 665 mm. The bike moves forward at 8.25 m/s. What is the wheel's centripetal acceleration?

Jolie the hamster is using his hamster wheel which has a diameter of 24.6 cm. A point on the wheel is moving at 0.17 m/s. What is the hamster wheel's centripetal acceleration?

Explanation / Answer

1) acceleration = v^2/r

a = 26.7^2/0.55 = 1296.16 m/s^2

2) a = 8.25^2/0.665 = 102.35 m/s^2

3) a = 0.17^2/0.123 = 0.235 m/s^2
