हिन्दीIn the given figure, \( a = 15 \text{ m/s}^2 \) represents the total acceleration of a particle moving in the clockwise direction in a circle of radius \( R = 2.5 \text{ m} \) at a given instant of time. The speed of the particle is
View Answer & Solution
Correct answer · Option C
\( 5.0 \text{ m/s} \)
Explanation
Given \( a_t = a \sin 30^\circ \). Also \( a_t = \frac{v^2}{R} \). Using \( a = 15 \text{ m/s}^2 \), we find \( v = \sqrt{15 \times \sin 30^\circ \times 2.5} \approx 5.0 \text{ m/s} \).
