Question

Step 1

Between *t =* 0 s and *t =* 10 s, the particle’s acceleration is 2 m/s^{2}.

Use kinematics’ first equation to find the velocity *v*_{10} of the particle at *t *=10.0 s as,

Step 2

Here, *v*_{0} is the particle’s velocity at *t = *0 s and *a*_{1} is the particle’s acceleration between 0 s and 10 s.

Between *t =* 10 s and *t =* 15 s, the particle’s acceleration is 0 m/s^{2}.

Use kinematics’ first equation to find the particle’s velocity *v*_{15} at *t *=15.0 s as,

Step 3

Here, *a*2 is the particle’s acceleration between 10 s and 15 s.

Between *t =* 15 s and *t =* 20 s, the particle’s acceleration is -3 m/s2.
