Question

A particle starting with an initial velocity \(2 \text{ ms}^{-1}\) moves with a uniform linear acceleration \(2 \text{ ms}^{-2}\). The particle velocities at the end of the 5 seconds and 10 seconds of its motion from the start, are in the ratio

• A. 1 : 2
• B. 11 : 16
• C. 6 : 11
• D. 2 : 1

Hint:

The ratio of velocities is not simply the ratio of times unless the initial velocity is zero. If \(u=0\), then \(v_1/v_2 = t_1/t_2 = 1/2\). Since \(u \neq 0\), the ratio shifts closer to 1.

Answer 1

The Correct Option is C
