Unformatted text preview: /fl\ 7. A car at the Indianapolis 500 mile race accelerates uniformly from the pit area, going from rest to 350 km/h in a semicircular arc with a radius of 275 m. Assume the tangential acceleration is constant around this turn. What is the tangential acceleration of the car throughout the turn? What is the tangential velocity of the car when it is 1/2 way through the turn? What is the radial acceleration of the car when it is 1/2 way through the turn? What is the magnitude and direction of the total acceleration when the car is 1/2 way through the turn? (Give the acceleration direction relative to the car’s velocity direction.) 3) VF 350000m/5taé‘03ea = €77.23m/3 “3?: WI” 3% 3 . 35%? 21,062 m? 52cm .mgwmlfidgifimfifi (‘33)2$;%_ 52 ray-5». move :5 a =1Jfa)’¢(§}’ 31W?” 8.
