A) You are driving at a constant velocity of magnitude v0 when you notice a garbagecan on the road in front of you. At that moment, the distance between the garbage can and thefront of the car is d. A time t after noticing the garbage can, you apply the brakes and slow downat a constant rate before coming to a halt just before the garbage can. B) Find the magnitude of ax, the acceleration of the car after the brakes are applied, in terms ofthe variables d, t, and v0 You should have found in part B. that ax = v20C) 2(d−v0t). Based on this expression, what happensto ax if t increases and all the other variables remain constant?i) decreases because it is inversely proportional to a linear function of t that increases as t increases.ii) increases because it is inversely proportional to a linear function of t that increases as t increases.iii) increases because it is a linear function of t.iv) decreases because it is inversely proportional to a linear function of t that decreases as t…
