Question I: Calculate the retarding force due to the viscosity of the air layer between a cart and a level air track given the following information-air temperature is 20°C, the cart is moving at 0.360 m/s, its surface area is 2.50×10-2 m2, and the thickness of the air layer is 5.10×10-5 m.
Question II: What is the ratio of this force to the weight of the 0.360-kg cart?
