An autonomous electromagnetic maglev freight sled is undergoing safety trials on a straight test track.
The graph shows the reaction distance (the distance travelled during signal transmission and processing delay) and the braking distance (the distance travelled while electromagnetic brakes are active) for the sled at different test speeds.
Describe the relationship between the speed of the sled and its reaction distance. Use data from the graph to support your answer.
Use the graph to find the reaction distance of the sled at a speed of 30 m/s30\text{ m/s}30 m/s.
Calculate the signal latency (reaction time) of the sled's receiver system at 30 m/s30\text{ m/s}30 m/s. Use the formula: distance=speed×time\text{distance} = \text{speed} \times \text{time}distance=speed×time Give your answer to 2 decimal places.
State one physical factor that increases the braking distance of the maglev sled.
Determine the total emergency stopping distance of the sled at a speed of 20 m/s20\text{ m/s}20 m/s. Use the graph to help you.
Explain how the speed of the sled affects its kinetic energy and braking distance. Use data from the graph to support your answer.
