A particle starts with an initial velocity of 10.0 ms⁻¹ along x -direction and accelerates uniformly at the rate of 2.0 ms⁻². The time taken by the particle to reach the velocity of 60.0 ms⁻¹ is __________. (a) 30s (b) 6s (c) 3s (d) 25s

Answer: (d). v = u + at 60 = 10 + 2t t = 25 s. So the answer is (d).

Equations of Kinematics

A particle starts with an initial velocity of $10.0\text{ ms}^{-1}$ along $x$ -direction and accelerates uniformly at the rate of $2.0\text{ ms}^{-2}$ . The time taken by the particle to reach the velocity of $60.0\text{ ms}^{-1}$ is __________.

Show answer and solution

Answer: (d)

$v = u + at$
$60 = 10 + 2t$
$t = 25\text{ s}$ . So the answer is (d).
