Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

It is autumn. You look outside a window and see a maple leaf falling face down, in a straight vertical line. You estimate the speed of the leaf to be 25.77 cm/s. You then pick up the leaf and do measurements. It has a mass of 2.76 g and a cross sectional area of 76 square cm. You measure the density of air to be 1.298 kg m-³. What is the drag coefficient between the leaf and the air? (numerical value only) Number (Hint: For an object to fall with constant speed, it must be at 'terminal velocity'.)

Kayaking is a great example of multiple drag forces. Where a person has to deal with currents in the water and air to propel themselves forward. In this problem, the water is moving at a velocity of 1.7 m/s directly in the direction you are trying to row. When considering this water, the area in contact with the water is .05 m^2, the drag coefficient is 1.02 with normal water density. You are moving at a velocity of 3 m/s, while the air is blowing against you with a velocity of 2.7 m/s (head wind). For the air, you have an area in contact of .5 m^2, and a drag coefficient of 1.75. Normal air density is present. In order to accomplish your time goal, you need a net force propelling you downstream of 175 newtons, how much force are you applying with the paddle to achieve this goal?
