To find x2, we first need to substitute 24-7t for t in x1.

x1 = 5t + 0.2t^2
x1 = 5(24-7t) + 0.2(24-7t)^2
x1 = 120 - 35t + 0.2(576 - 336t + 49t^2)
x1 = 120 - 35t + 115.2 - 67.2t + 9.8t^2
x1 = 235.2 - 102.2t + 9.8t^2

So, x2 = 235.2 - 102.2t + 9.8t^2

The units of x1 and x2 are not provided, so it is not possible to determine the units for s.
