1.	The displacement of a particle is given by x(t) = (4t ^(2) +8)meter. The instantaneous velocity of a particle at t = 2s is
Answer» 12m/s 16m/s 8cm/s 16 cm/s Solution :Here,` x (t) = 4t ^(2) + 8M` is given, `therefore` Instantaneous velocity `v = (DX )/(dl) = (d)/(DT) (4t ^(2) +8)` `therefore v = 8T` So, at` t = 2s, v = 8(2) = 16 m//s`
