Solve the problem.Given the acceleration, initial velocity, and initial position of a body moving along a coordinate line at time t, find the body's position at time t.a = 16 cos 2t, v(0) = 9, s(0) = -11
A. s = 4 cos 2t - 9t - 7 B. s = 4 sin 2t + 9t - 7 C. s = - 4 sin 2t + 9t - 7 D. s = - 4 cos 2t + 9t - 7
