हिन्दीA car accelerates uniformly from rest at \( 2.5\text{ m s}^{-2} \) for \( 6.0\text{ s} \). What is the average velocity of the car during this time interval?
View Answer & Solution
Correct answer · Option B
\( 7.5 m s$^{-1}$ \)
Explanation
Final velocity \( v = at = 2.5 \times 6 = 15\text{ m s}^{-1} \). Average velocity for constant acceleration is \( \frac{v_0 + v}{2} = \frac{0 + 15}{2} = 7.5\text{ m s}^{-1} \).
