Question
A graphing calculator is recommended.
An elastic band is hung on a hook and a mass is hung on the lower end of the band. When the mass is pulled downward and then released, it vibrates vertically. The equation
of motion is s(t)
9 cos(t) + 8 sin(t), t > 0, where s is measured in centimeters and t in seconds. (Take the positive direction to be downward.)
(a) Find the velocity and acceleration at time t.
v(t) = -9 sin(t)+ 8 cos (t)
a(t) = -9 cos(1) – 8 sin(t)
