Q1. The speedometer of a truck shows the linear velocity of the truck but actually measures the angular velocity of the wheels and converts that to the linear velocity. If the tires are changed out and larger diameter tires replace the stock tires, does this affect an accuracy of the speedometer? B) Is the true linear speed greater, less or same as the speedometer reading?
Q2. What will be the acceleration of a turtle that is moving with a constant velocity of 0.333 m/s to the right?
