Question
At what time was its velocity greatest? 48 m
During what periods, if any, was the acceleration constant?
Check all that apply
from t = 110 s to t ? 125 s
from t = 42 s to t ? 65 s
from t = 0 s to t ? 42 s
from t ? 65 s to t ? 83 s
from t = 90 s to t ? 108 s
When was the magnitude of the acceleration greatest?

Check all that apply When was the magnitude of the acceleration greatest?Explanation / Answer
accelration is constant means slope constant.
so where v-t curve is a straight line.
t = 0 to 42 sec
t = 65 to 83
t = 90 to 108
magnitude max. means slope max.
that is t = 65 to 83
