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 = 6 cos(t) + 3 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. g

Explanation:

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 given by :

Where

s is in centimeters

t is in seconds

Velocity of the particle,

Acceleration of the particle,

Hence, this is the required solution.

the answer is c i did the same question so i know that's right!

c, 1a hope this
