In Fig. on the right, what is the acceleration at 1.0 s?

10 m/s²

Explanation:

Acceleration is the slope of the velocity vs time graph.

At t = 1.0 s, the slope of the line is:

a = Δv/Δt

a = (20 m/s) / (2.0 s)

a = 10 m/s²

10m/s2

Explanation:

Acceleration is defined as change in velocity over the time period

Now at 1second the velocity is 10m/s.

Hence the acceleration is V-U/t;

Where V is velocity at 10s and U is velocity when the object is at rest.

So we have;

Acceleration = 10-0/ 1 = 10m/s2
