The car rounds a circular track of radius 300.0 m at a speed of 90.0 km/h. Riders feel as if they are pinned to the wall by a force something like the gravitational force. The path of the coaster from its initial point shown in the figure to point B involves only up-and-down motion (as seen by the riders), with no motion to the left or right. She has a lunch box resting on wax paper, so that there is very little friction between it and the merry-go-round. Because there is no friction over this portion of the track, the only energy conversion that takes place is between kinetic energy and gravitational potential energy. Two muscles in the back of the leg pull upward on the Achilles tendon, as shown below. How does Charle's law relate to breathing? The coefficient of friction is80%80%of that for the static case. Do you feel yourself thrown to either side when you negotiate a curve that is ideally banked for your cars speed?
