A body A starts from rest with an acceleration a_1 . After 2 seconds, another body B starts from rest with an acceleration a_2 . If they travel equal distances in the 5th second, after the start of A, then the ratio \(\vec{a}_1 \cdot \vec{a}_2\) is equal to
Text Solution
Verified by ExpertsThe correct answer is:
A
According to problem Distance travelled by body A in 5^{th} sec and distance travelled by body B in 3^{rd} sec . of its motion are equal.
\(0 + \frac{a_1}{2} (2 \times 5 - 1) = 0 + \frac{a_2}{2} [2 \times 3 - 1]\)
\(9a_1 = 5a_2 \implies \frac{a_1}{a_2} = \frac{9}{5}\)
