2. (5 pts) You are driving on a long straight road at a constant speed of 30 \( \mathrm{m} / \mathrm{s} \). At time \( \mathrm{t}=0 \) you pass a sign that says the speed limit is only \( 25 \mathrm{~m} / \mathrm{s} \). 50 meters after you pass the sign you begin to slow down with an acceleration of \( -1 \mathrm{~m} / \mathrm{s}^{2} \). At what time will you be driving at the speed limit of \( 25 \mathrm{~m} / \mathrm{s} \) ?
