Your car's speedometer works in much the same way as its odometer, except that it converts the angular speed of the wheels to a linear speed of the car, assuming standard-size tires and no slipping on the pavement.
If your car has standard 24.0 inch-diameter tires, how fast are your wheels turning when you are driving at a freeway speed of 58.0 mph?
How fast are you going when your wheels are turning at 520 rpm?
If you put on undersize 20.0 inch-diameter tires, what will the speedometer read when you are actually traveling at 50.0 mph?
The gravitational acceleration on the Moon is a sixth of that on Earth. The weight of an apple is 1.03 N on Earth. What is the mass of the apple
A 68.0 kg person escapes from a burning building by jumping from a window 25m above a catching net. Assuming that air resistance exerts a 95N force on the person during the fall, determine the person's velocity just before hitting the net.

One tire is inflated to a pressure of 40 and goes a distance of 18.0 ; the other is at 105 and goes a distance of 93.4. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be = 9.80.
