A car traveling at 30.0 km/h speeds up to 40.0 kmi/h in a time of 6.00 s. The same car later speeds up from 60.0 km/h to 70.0 km/h in a time of 6.00 s. Let the +x direction point in the direction the car is traveling. Calculate the magnitude a, of the constant acceleration for the first time interval. al = m Determine the distance d, traveled by the car during the first time interval. di = Calculate the magnitude a2 of the constant acceleration for the second time interval. a2 : m/s Determine the distance d2 traveled by the car during the second time interval. d2 =
