Physics - Kinematics Question with Solution | TestHub

A stone is projected from level ground at $\mathrm{t}=0$ sec such that its horizontal and vertical components of initial velocity are 10 m/s and 20 m/s respectively. Then the instant of time at which magnitude of tangential and magnitude of normal components of acceleration of stone are same is : (neglect air resistance) $g=10\mathrm{m}/{\mathrm{s}}^2$.
