Solve the initial value problem.
= -18cos (3t), s '(0) = 11, s(0) = 8
A. s = 2 cos (3t) + 6 B. s = 2 cos (3t) + 11t + 6 C. s = -6 sin (3t) + 11 D. s = 6 cos (3t) + 11t + 2
Solve the problem. Assume the x-axis is horizontal, the positive y-axis is vertical (opposite g), the ground is horizontal, and only the gravitational force acts on the objects. A projectile is launched from the origin at an angle of ? radians to the horizontal and an initial speed of 
Find the position function r(t) for this projectile.
A. r(t) = (175t cos ?)i + (175t sin ? - 16t2)j B. r(t) = (175t sin ? - 16t2)i + (175t cos ?)j C. r(t) = (175t sin ?)i + (175t cos ? - 16t2)j D. r(t) = (175t cos ? - 32t2)i + (175t sin ?)j
