Physics - Kinematics Question with Solution | TestHub

A Diwali rocket moves up with a constant acceleration ${\mathrm{a}}_1=20/3\mathrm{m}/{\mathrm{s}}^2$. After some time its fuel gets exhausted and then it falls freely. If the maximum height attained is 50 m and if $\mathrm{v}(\mathrm{in}\mathrm{m}/\mathrm{s})$ is speed when the fuel is exhausted. Find the value of $\frac{\mathrm{v}}{10}$.
