A high-speed pneumatic delivery capsule travels 8.4 km from Hub Alpha to Hub Beta. The journey takes 7 minutes.
State the equation linking average speed, distance moved and time taken.
Calculate the average speed of the capsule and state its unit.
The maximum speed of the capsule must be higher than the average speed you calculated. Explain why.
The capsule continues along a straight guideway from Hub Beta to Hub Gamma.
The graph shows how the velocity of the capsule changes with time during this part of the journey.
Use the graph to calculate the acceleration of the capsule, in m/s2\text{m/s}^2m/s2, during the first 50 seconds after it leaves Hub Beta.
Use the graph to calculate the distance, in m, between Hub Beta and Hub Gamma.
