A particle is in motion, and its acceleration at t sec is found to be
a(t) = (3(-1 + t) cos(t))i + (9(-1 + t)t)j + (9 sin(t))k.
If it was at position (3, 4, 2) with velocity (4, -4, 4) when t = 0, what are the velocity and position
vectors when t = 1.1 sec?
Typesetting: Enter your answer with parentheses such as '<1,2,3>',
velocity: <2.628,-5.452,8.918>
position: (6.311,-2.498,8.279)
