Weba2 = ax2 + ay2. a2 = [− r ω 2 cos (ω t )] 2 + [− r ω 2 sin (ω t )] 2. ac = r ω 2. Speed has a constant value, but direction is changing. There is an acceleration and that's its equation. If you don't like angular quantities, you can use algebra to state centripetal acceleration in terms of tangential velocity. Web5. A plane comes out of a power dive, turning upward in a curve whose center of curvature is 1300 m above the plane. The plane's speed is 260 m/s. a. Calculate the upward force of the seat cushion on the 100 kg pilot of the plane. b. Calculate the upward force on a 90.0 g sample of blood in the pilot's head. kg ms N m kg m s mg R mv F (100 )( 9 ... WebNov 5, 2024 · If centripetal force is directed toward the center, why do you feel that you are ‘thrown’ away from the center as a car goes around a curve? Explain. 6. Race car drivers routinely cut corners as shown in Figure. Explain how this allows the curve to be taken at the greatest speed. Two paths around a race track curve are shown. how to make web crawler
