let the acceleration be a , (I expect a to be negative)
v = at + c
when t = 0 , v = 8
8 = 0+c ---> c = 0
so v = at + 8
when t = .36, v = 0
0 = a(.36) + 8
a = -8/.36 = appr -22.2 m/s^2
v = at + c
when t = 0 , v = 8
8 = 0+c ---> c = 0
so v = at + 8
when t = .36, v = 0
0 = a(.36) + 8
a = -8/.36 = appr -22.2 m/s^2
