Question

The velocity of a particle moving in positive x-axis
is according to relation v = √4x. If at t = 0
particle is at x = 0, then the velocity and
acceleration at t = 2s are given as
(1) 4 m/s, 4 m/s2 (2) 2 m/s, 2 m/s2
(3) 2 m/s, 4 m/s2 (4) 4 m/s, 2 m/s2​

Answer 1

The velocity of a particle moving in positive x-axis

is according to relation v = √4x. If at t = 0

particle is at x = 0, then the velocity and

acceleration at t = 2s are given as

(1) 4 m/s, 4 m/s2

(2) 2 m/s, 2 m/s2

(3) 2 m/s, 4 m/s2 ✔️✔️✔️

(4) 4 m/s, 2 m/s2
