4.Jessica Diggins a US world champion cross country skier is participating in the winter Olympic games. Over a 200m stretch in her race she increases her speed with a constant acceleration from 5.1 m/s to 6.2 m/s over a period of 25 seconds. What is her acceleration

Respuesta :

Answer:

[tex]a=0.044\ m/s^2[/tex]

Explanation:

Given that,

Initial speed, u = 5.1 m/s

Final speed, v = 6.2 m/s

Time, t = 25 s

We need to find acceleration. We know that,

acceleration = rate of change of velocity

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{6.2-5.1}{25}\\\\a=0.044\ m/s^2[/tex]

So, her acceleration is [tex]0.044\ m/s^2[/tex].
