Answer:
[tex]0.5 m/s^2[/tex]
Explanation:
The acceleration of an object is given by the equation
[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 for the velocity to change from u to v
For the skater in this problem we have:
u = 0 (assuming it starts from rest)
v = 6 m/s is the final velocity of the skater
t = 12 s is the time taken
Substituting, we find
[tex]a=\frac{6-0}{12}=0.5 m/s^2[/tex]
