Answer:
6.64 m/s^2
Explanation:
Average acceleration is defined as follows:
[tex]a=\frac{v-u}{t}[/tex]
where
v is the final velocity of the object
u is the initial velocity
t is the time taken to accelerate from u to v
In this problem, we have:
[tex]u=0 m/s[/tex] (the motorcycle starts from rest)
[tex]v=28.0 m/s[/tex] is the final velocity
[tex]t=4.22 s[/tex] is the time taken
Substituting numbers into the formula, we find
[tex]a=\frac{28.0 m/s-0}{4.22 s}=6.64 m/s^2[/tex]
