- Question #2: A Tesla Model 3 is driving down Bank Street in Ottawa, Ontario. It is driving along with zero acceleration. A pedestrian, without looking, runs into the road right in front of the oncoming Model 3. The Forward Collision Warning sounds, and the Automatic Emergency Braking software comes into affect, applying the brakes to avoid hitting the pedestrian. The Model 3 applies the brakes until the pedestrian makes the Model 3's original driving speed of 54 [km/h]. Based on following graph, we assume to the other side of the road, and then the driver accelerates to reach 1) when x = 0, t = 0 2) when 0 < t < 1, the acceleration is zero. 3) At t= 1 s, the braking system is activated.

Starting from rest, the shuttle accelerates at 0.447 m/s2 for 37.1 s, cruises at this constent velocity for 62.5 s, and then deaccelerates at -0.275 m/s2 until it comes to a stop.

The test engineer sets up the rocket horizontally on a cart that runs along a straight track with very little friction. She set up a timer and a radar speed gun at the end of the track.

The engineer of the passenger train immediately applies the brakes causing a constant acceleration of 0.100 m/s in a direction opposite to the train’s velocity, while the freight train continues with constant speed.
