Given equation,

x = 10cos(2t + π/2)

Differentiating both sides of the equation with respect to time.

We get,

v = 10 × 2 -Sin(2t + π/2)

∴ v =  -20Sin(2t + π/2)

v =  -20Sin(2 × 1/6  + π/2)

∴ v = -20Sin( π/2 + 1/3)

v = -20Cos(1/3)

v = -20 × 0.18

∴ v = -3.60 m/s.


Hence, the velocity of the particle at time 1/6 seconds is 3.6 m/s.


Hope it helps .
