<em>800 km/h</em>
<em>Hi there ! </em>
<em>1 hour = 60 min</em>
<em>30 min = 0.5 hour</em>
<em />
<em>400 km ............ 0.5 h</em>
<em> x km .............. 1 h</em>
<em />
<em>x = 400km×1h/0.5h</em>
<em>= 800 km/h</em>
<em />
<em>Good luck</em>
The distance the ball rolls is given by
<em>x</em> = 1/2 <em>a</em> <em>t</em>²
so that
<em>x</em> = 1/2 * (3.3 m/s²) * (7.5 s)² = 92.8125 m ≈ 93 m
