For a particle moving along a straight line, its velocity 'u' and displacement '.s' are related as u2 = cs, here c is a constant. If the displacement of the particle at t = 0 is zero, its velocity after 2 second is:

v2 = cs ⇒ Acceleration =c2 so from v = u + at, at t= 2s,v = 0+ c2(2) =c

Detailed Solution

v² = cs $\Rightarrow$ Acceleration = $\frac{c}{2}$ so from v = u + at, at t= 2s,
v = 0+ $\frac{c}{2}$ (2) =c
