The initial speed of the boat is [tex]v_0=10 m/s[/tex]
and its acceleration is [tex]a=5.0 m/s^2[/tex]
Since the boat is moving by uniform accelerated motion, the distance covered by the boat in a time t=10 s is given by:
[tex]S(t)=v_0 t + \frac{1}{2}at^2 = (10 m/s)(10 s)+ \frac{1}{2}(5m/s^2)(10s)^2 =350 m [/tex]
So, the boat covers a distance of 350 m in 10 seconds.
