Physics · MOTION IN A STRAIGHT LINE
हिन्दीA car starting with an initial velocity \( v_0 = 5\text{ m s}^{-1} \) accelerates uniformly at \( a = 3\text{ m s}^{-2} \) along a straight road. What is its velocity after a time interval \( t = 6\text{ s} \)?
Correct answer · Option A
\( 23\text{ m s}^{-1} \)
Explanation
Using the kinematic relation \( v = v_0 + at \), we get \( v = 5 + 3 \times 6 = 5 + 18 = 23\text{ m s}^{-1} \).
