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 26.3 m/s. What is the centripetal acceleration of the tire which has a radius of 0.41 m?

Arek is riding his bicycle on a non-slippery bike path. The wheel has a radius of 721 mm. The bike moves forward at 7.15 m/s. What is the wheel's centripetal acceleration?

Jolie the hamster is using his hamster wheel which has a diameter of 23.6 cm. A point on the wheel is moving at 0.13 m/s. What is the hamster wheel's centripetal acceleration?

Explanation / Answer

yelena:

ac=v2/r

ac=23.62/0.41

ac=1358.4390 m/s2

arek:

ac= 7.152/0.721 (721mm=0.721m)

ac=709 m/s2

jolie:

diametre=23.6cm

radius=diametre/2

radius=11.8cm

radius=0.0118m

ac=v2/r

ac=0.132/0.0118

ac=1.432m/s2
