A particle is moving with speed v = b x along positive x - axis. Calculate the speed of the particle at time t = τ (assume that the particle is at origin at t = 0 )

Question

A particle is moving with speed v = b x along positive x - axis. Calculate the speed of the particle at time t = τ (assume that the particle is at origin at t = 0 ), b 2 τ, b 2 τ 2, b 2 τ 2, b 2 τ 4

MARKS App · Accepted Answer

v = b x … (1) ⇒ d x d t = b x d x x = b d t ∫ 0 x d x x = ∫ 0 t b d t 2 x = b t … (2) From equation (1) and (2) v = b b t 2 ∴ a t t = τ v = b 2 τ 2
