Final answer:

To solve for time t, we use the known values of initial velocity, acceleration, and displacement in the kinematic equation x = xo + vot + 1/2at². The result is a quadratic equation that we solve to find the value(s) of time t.

Step-by-step explanation:

To solve for the time t, we must use an equation that relates the variables we know: initial velocity vo, acceleration a, and displacement x. The question presents the knowns as vo = 10 m/s, a = 2.00 m/s², and x = 200 m. The equation that fits this scenario is x = xo + vot + 1/2at². Our goal is to find t.

Given the equation and known values, we substitute and rearrange to find t as follows:

  1. Substitute known values into the equation: 200 m = 0 m + (10.0 m/s)t + (1/2)(2.00 m/s²)t²
  2. Simplify the equation: 200 m = 10t + t²
  3. Rearrange the quadratic equation to solve for t: 0 = t² + 10t - 200
  4. Solve the quadratic equation using the quadratic formula or other methods to find the value(s) of t.

Upon solving this equation, we can determine the unknown time t.
