During the first interval from 0 to 10 s, the acceleration is constant, and we know that x = x₂ + Vox At+ax(At)² while vx = Vox + axt.

Write an expression for the x-position as a function of time t for the first interval, i.e., for 0 < t < 10 s. Your expression should only contain the variablet and the correct values (with units) of the constants xo. Vox, and a. Assume x = 0 at t = 0.
