Question

Mf displacement of a particle varies with time as
√x = 2t +7, velocity of particle is proportional to
(1)√ x
(2) X
(3) x2
(4) 1/x answer is √x guys plss fully explain fast. need help​

Answer 1

Explanation:

√x=t+7

x = ( t+7)2

V= dx/dt = 2 (t+7)

Thus, Velocity is proportional to time.

Also as a = dv/dt = 2

Thus Particle moves with a constant acceleration.

Hence Proved .
