A car travels on the entrance ramp to a freeway as it accelerates from 30 mph to the freeway speed of 70 mph for 4.0 s. Suppose that the car moves with the constant acceleration. Part A Estimate the distance in feet that the car travels during this motion. Express your answer in feet. ANSWER: d = ft Part B During this motion what is the magnitude of the average acceleration of the car? Express your answer in feet per second squared. ANSWER: Aav = ft/s?
