Question

1.      A car at the Indianapolis 500 milerace accelerates uniformly from the pit area, going

       from rest to 350 km/h in asemicircular arc with a radius of 275 m. Assume the

       tangential acceleration isconstant around this turn.

a.       What is the tangentialacceleration of the car throughout the turn?

b.      What is the tangential velocity ofthe car when it is ½ way through the turn?

        c.   Whatis the radial acceleration of the car when it is ½ waythrough the turn?

        d.   Whatis the magnitude and direction of the total acceleration when thecar is

             ½ way through the turn? (Give the accelerationdirection relative to the car’s

             velocity direction.)
