Focus on 3rd and 4th question 3.You are driving at a constant velocity of magnitude vo 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.3a.

3c. Find the magnitude of ar, the acceleration of the car after the brakes are applied, in terms of the variables d, t, and vo. Based on this expression, what happens v 3d. You should have found in part 3c. that ar 2(d-vot) to az 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 in- creases. v) increases because it is inversely proportional to a linear function of t that decreases as t increases.
