The velocity of a pendulum changes at a rate of a(t) = 0.9' cos(0.2t) meters per second
squared (where t is the time in seconds). At time t = 6, the velocity of the pendulum is 0.8
meters per second. By how much does the velocity change between t = 6 and t = 12
seconds?
Which expression can we use to solve the problem?
