average velocity is __ 40.0 m / 9.40 s
average equals initial plus final, divided by two
40.0 / 9.40 = (i + 2.35) / 2 __ i = 6.16
acceleration equals final minus initial, divided by time
a = (2.35 - 6.160 / 9.40
average equals initial plus final, divided by two
40.0 / 9.40 = (i + 2.35) / 2 __ i = 6.16
acceleration equals final minus initial, divided by time
a = (2.35 - 6.160 / 9.40
