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?

from t = 42 s to t ? 65 s from t = 110 s to t ? 125 s from t = 0 s to t ? 42 s from t = 90 s to t ? 108 s from t ? 65 s to t ? 83 s At what time was its velocity greatest? 48 m During what periods, if any, was the acceleration constant?

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
