Song JI Hyo ride a roller coaster during her visit to gentig highland theme park. the roller coaster moves with a(t)= e^2t+1 . i +(1-2t^3).k, where t is measured in second and the vertor components measured in meter. Find her position at t=2 given initial condition v(0)=i+j+2k and r(0)01/2e^1 . i + 10.j.
