Question 11

Multiple Choice

If the mass in the previous problem is pulled down two centimeters and released, the solution for the position is


A) x=0.02e2t+0.04te2tx = 0.02 e ^ { - 2 t } + 0.04 t e ^ { - 2 t }
B) x=2e2t+4te2tx = 2 e ^ { - 2 t } + 4 t e ^ { - 2 t }
C) x=0.02e2t0.04te2tx = 0.02 e ^ { 2 t } - 0.04 t e ^ { 2 t }
D) x=e2tsintx = e ^ { - 2 t } \sin t
E) x=0.02e2tcostx = 0.02 e ^ { - 2 t } \cos t
