A particle is projected at an angle of 60o above the horizontal with a speed of 10 m/s. After some time the direction of its velocity makes an angle of 30o above the horizontal. The speed of the particle at this instant is
- \(\frac{5}{\sqrt{3}} \mathrm{~m} / \mathrm{s}\)
- \(5 \sqrt{3} \mathrm{~m} / \mathrm{s}\)
- 5 m/s
- \(\frac{10}{\sqrt{3}} \mathrm{~m} / \mathrm{s}\)
Answer
(D) 10 3 ~m / s
