Question

At time t=0, a particle leaves the point with position vector R(0) with initial velocity v(0). For all t (greater than or equal to) 0, when;
R(0)=0,
v(0)=2i+k
a(t)= -2cos(t)i-2sin(t)j

Answer 1

what do we have to find?

Answer 2

Oh sorry, I'm trying to find expressions for the position R(t) and the velocity v(t).

I started by taking the integral of a(t).

Answer 3

yea thats right... :).. all you gotta do is integrate!
