Answer:
72 m
Explanation:
Assuming the motorcyclist is travelling at constant acceleration, we can find the distance travelled by using the following suvat equation:
[tex]d=(\frac{u+v}{2})t[/tex]
where
d is the distance travelled
u is the initial velocity
v is the final velocity
t is the time interval
In this problem we have
u = 9 m/s
v = 15 m/s
t = 6 s (we are only interested in the time interval in which the velocity changes from 9 m/s to 15 m/s)
Substituting we find
[tex]d=(\frac{9+15}{2})(6)=72 m[/tex]
