Question

The graph gives the velocity v versus time t for a particle moving along an x axis. What is the particle's displacement from t = 0 to t = 16 s ?

Answer 1

`380"m"`

Explanation:

The total distance travelled = the area under the velocity / time graph.

From this you can see that:

`s=(40xx5)/(2) +(3xx40)+(8xx40)/(2)`

`=100+120+160=380"m"`
