The exact cart position 2.0 seconds later is 9.0 m.
To find the exact cart position 2.0 seconds later, we can use the formula: x = x0 + vt, where x is the final position, x0 is the initial position, v is the velocity, and t is the time. In this case, the initial position, x0, is 5.0 m, the velocity, v, is 2.0 m/s, and the time, t, is 2.0 s.
Plugging in the values, we have:
x = 5.0 m + (2.0 m/s)(2.0 s) = 5.0 m + 4.0 m = 9.0 m
