Question

I need help with nine and 10 I will really appreciate it

Answer 1

9] V =
`(D)/(T)`

Take any distance value from the graph and its relevant time.

V =
`(8)/(4)`

V = 2 m/s

[You will notice that any distance values with its time will give you 2 m/s as its speed. This means that speed is constant throughout.]

10] Take the distance value and its time for the highest peak of B.

V =
`(20)/(2)`

V = 10 m/s
