NEET 2014 Physics Average Velocity MCQ Question
A particle is moving such that its position coordinates (x, y) are (2m, 3m) at time t = 0; (6m, 7m) at time t = 2 s and (13m, 14m) at time t = 5 s. Average velocity vector v̅ₐᵥ from t = 0 to t = 5 s is
1/5 (13î + 14ĵ)
7/3 (î + ĵ)
2 (î + ĵ)
11/5 (î + ĵ)
Correct Answer
Detailed Explanation
The average velocity is calculated by taking the change in position over the change in time. From t = 0 to t = 5 s, the change in position is (13 - 2, 14 - 3) = (11, 11). Dividing by the time interval 5 s gives the average velocity vector as 1/5 (11î + 11ĵ) = 1/5 (13î + 14ĵ).
