turner's treadmill..?

Question

Turner's treadmill starts with a velocity of -2.6m/s and speeds up at regular intervals during a half-hour workout. after 37min. the treadmill has a velocity of -8.4m/s. what is the average acceleration of the treadmill during this period?

Answer 1

The equation for this is:

v(t)=v0+a*t

in this case
-8.4=-2.6+a*37*60
a=-11/(37*60)
