Answer:
63 m
Explanation:
The initial velocity of the motorcycle is
[tex]v_i = 21 m/s[/tex]
The final velocity is
[tex]v_f = 0[/tex]
And the time taken is
[tex]t=6.0 s[/tex]
Since the acceleration of the motorcycle is uniform, we can find the distance traveled by the motorcycle during this time by using the following SUVAT equation:
[tex]S=\frac{1}{2} (v_i +v_f) t[/tex]
Substituting numbers into the equation, we find
[tex]S=\frac{1}{2}( 21 m/s + 0)(6.0 s)=63 m[/tex]
