3. A car accelerates in the +x direction from rest with a constant acceleration of a = 1.52 m/s for t=20 s. At that point the driver notices a tree limb that has fallen on the road and brakes hard for 12 = 5 s until it comes to a stop. (a) What is the car's speed just before the driver begins braking? X-XO Equation to use: (b) What is the distance travelled by the car during this period of acceleration? Vo 4. This is a continuation of problem 3. You can use all the information given and your result from problem 3. (a) What is the distance traveled by the car during the time when the driver steps on the brake? X-XO Equation to use: Vo V a (b) If the limb is on the road at a distance of 550 meters from where the car began its initial acceleration. How far, in meters, from the original location of the limb will the car be when it stops? 3. A car accelerates in the +x direction from rest with a constant acceleration of a = 1.52 m/s for t=20 s.
