If the velocity of a particle is (10 + 2 t 2 ) m/s , then the average acceleration of the particle between 2s and 5 s is
Text Solution
Verified by ExpertsThe correct answer is:
D
Average acceleration \(\frac{\text{Change in velocity}}{\text{Time taken}}\) \(= \frac{V_{2} - V_{1}}{t_{2} - t_{1}}\) \(= \frac{\left[ 10 + 2(5)^2 \right] - \left[ 10 + 2(2)^2 \right]}{3} = \frac{60 - 18}{3}\) \(= 14 \, m/s^{2}\) .
