5. [1 mark] Sketch the velocity-versus-time graph for a car that accelerates uniformly from rest to 30 m/s in 5 seconds. The car remains at this constant velocity for the next 6 seconds. During the following 9 seconds, the car then slows down uniformly until its velocity become -10 m/s. During the last 3 seconds, the car comes to a complete stop uniformly.

3. You are driving to the store at a constant velocity of 60.0 km/h East when you see a squirrel run into the middle of the road. It takes you 200.0 ms for you to react and to begin applying the brakes. Once you start braking, you accelerate uniformly to rest in 2.00 seconds. a) Sketch the velocity-time and position-time graphs for your car from the moment you saw the squirrel. [East] [East] b) Briefly explain the analysis you would perform to find the total displacement of the train over the trip described. (No calculations are required).
