Physics - Kinematics Question with Solution | TestHub

The body moves along the $x$-axis. At time $t=0$, the velocity of the particle is $+5.0\mathrm{m}/\mathrm{s}$. The acceleration of the particle in different time intervals is given as:

$$a(t)=\{\begin{array}{ll}-2{m/s}^2& 0s\le t\le 3\mathrm{s}\\ -4{m/s}^2& 3s<t\le 6\mathrm{s}\\ +6{m/s}^2& 6s<t\le 10\mathrm{s}\end{array}$$
