WebAssume minimal energy losses due to air resistance, rolling resistance, or other forms of friction and answer the following questions. Determine the speed of the coaster at the top of the loop if the normal force of the rails on the wheels is half the weight of the coaster (that is, if the frame of reference acceleration is ½g). WebSkin friction: This type of air resistance is caused by the friction between the air molecules and the surface of the object. As an object moves through the air, the air molecules closest to the surface of the object are slowed down by the frictional force, which in turn slows down the object. The amount of skin friction depends on the ...
