there are three questions to this problem, but i will ask the first one first.

1.)What is the maximum speed attained?

using the formula d1 = x(0) +v(0)*t + 1/2at^2

x(0) = 0 because the velocity is zero

d1 = 1/2(19.8) * (15.9 *60)^2 <--- converted to secs.

well that's the speed for distance #1, but since it's constant just before it reaches distance #3, shouldnt that be the maximum speed?
