1) Find the position vector R(t) given the velocity V(t)=(4t+3)i+6sin(3t)j+4tk and the initial position vector R(0)=3i-3j-3k. R(t)= 2) Find the position vector R(t) given the velocity V(t)=16e^(4)ti+25cos(5t)j+15t^(2)k and the initial position vector R(0)=2i+2j-k. R(t) 3) Find the position vector R(t) and velocity V(t) given the acceleration A(t)=16e^(-2t)i+16cos(4t)j+20t^(3)k and the initial velocity vector V(0)=-i-3j+2k and initial position vector R(0)=-3i-j+2k. V(t)= R(t)=
