Answer:
[tex]1 m/s^2[/tex]
Explanation:
The acceleration of an object is the rate of change of velocity of the object; it is given by:
[tex]a=\frac{v-u}{t}[/tex]
where
u is the initial velocity of the body
v is its final velocity
t is the time elapsed
In this problem, we have:
u = 5.0 m/s is the initial velocity of the skater
v = 10.0 m/s is the final velocity
t = 5 s is the time elapsed
Therefore, the acceleration of the skater is:
[tex]a=\frac{10-5}{5}=1 m/s^2[/tex]
