A stone is projected from the ground with velocity \(25 \, m/s\) . Two seconds later, it just clears a wall 5 m high. The angle of projection of the stone is (g = 10 m/sec^{2})
Text Solution
Verified by ExpertsThe correct answer is:
A
For vertical upward motion \(h = ut - \frac{1}{2}gt^{2}\)
\(5 = (25 \sin \theta) \times 2 - \frac{1}{2} \times 10 \times (2)^2\)
⇒ ⇒ 25 = 50 sin θ θ ⇒ ⇒ \(\sin \theta = \frac{1}{2}\) ⇒ ⇒ \(\theta = 30^\circ\)
