6it'll be better if u post wat u hav done so that we can see where u r wrong...
1. The co-ordinate of a moving particle in x-y plane at any time "t" are
(2t,t2)
find the velocity of the particle and the acceleration of the particle?
2. After what time the particle will acquire initial velocity from the given fig?
please give detailed solution...

61for the second one
it must b after extra time 'x'=√12≈3.4641
t=2+√3≈5.4641
for the first one take unit vectors along x and y [i(cap)]&[j(cap)]
displacement s=2t[i(cap)]+t2[j(cap)]
velocity v=dsdt=2[i(cap)]+2t[j(cap)]
acceleration a=2[j(cap)]
