Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

The speed-time graph in the question ... The bus has a constant speed of \(5 m\,s^{-1}\). f) BC. The bus is slowing down so it has a negative acceleration. This type of acceleration is sometimes ...

Let me start with a graph. This shows the horizontal acceleration of the pod as a function of time. Here the pod accelerates at 9.8 m/s 2 for 2.6 minutes and then travels at a constant speed.
