The graph shows the thinking and braking distances for an electric quadricycle at different speeds.
Describe how thinking distance varies with increasing speed. Use data from the graph to support your answer.
Use the graph to find the thinking distance at 15 m/s15 \text{ m/s}15 m/s.
Calculate the thinking time (reaction time) at 15 m/s15 \text{ m/s}15 m/s. Use the equation: distance travelled=speed×time\text{distance travelled} = \text{speed} \times \text{time}distance travelled=speed×time Give your answer to 2 decimal places.
State one factor that could increase thinking distance.
Calculate the stopping distance at 20 m/s20 \text{ m/s}20 m/s. Use the graph to help you.
How does the speed affect the kinetic energy and braking distance of the electric quadricycle? Use the graph to support your answer.
