Answer:A particle has zero velocity initially (i.e., at time
t=0
t=0
) and its acceleration at
t
t
seconds is
a(t)=72t−4
t
3
a(t)=72t−4t3
meters-per-second per second. During the time interval
[5,8]
[5,8]
seconds find the average acceleration and the average speed of the particle. I got the average acceleration by taking the integral and then plugging that into
f(8)−f(5)/8−5
f(8)−f(5)/8−5
but I have tried working through the average speed and I can't find the answer for that one.
