Question 11

An autonomous electric cargo pod is undergoing safety tests on a guided track. During an emergency stop sequence, the onboard control system must detect an obstacle and activate the brakes to bring the pod to a halt.

a.

Explain the factors that affect the 'reaction distance' (the distance travelled between detecting the obstacle and the brakes being fully applied) and the 'braking distance' of the pod.

[6]
b.

Write down the equation that links distance, force, and work done.

[1]
c.

In one emergency stop test, the work done by the braking system to stop the pod is 540 000 J540\,000\text{ J}540000 J. The average braking force applied by the pod's brakes is 15 000 N15\,000\text{ N}15000 N. Calculate the braking distance of the pod.

[3]
d.

If the braking system applies an extremely large force, it results in rapid deceleration. Explain the potential hazards to the pod's stability, control, or cargo from such a violent deceleration.
