Motion in A Plane question

2023 · 11 Apr · Shift 1 · Q69

JEE MainPhysicsMotion in A PlaneNumerical+4 / −1
A projectile fired at 30∘30^{\circ}30∘ to the ground is observed to be at same height at time 3 s3 \mathrm{~s}3 s and 5 s5 \mathrm{~s}5 s after projection, during its flight. The speed of projection of the projectile is ‾\underline{\hspace{2cm}}​m s−1\mathrm{m} ~\mathrm{s}^{-1}m s−1. (Given g=10 ms−2g=10 \mathrm{~ms}^{-2}g=10 ms−2 )
