A physics student running 2.8 m/s increases her velocity to 4.7 m/s in 3.4 seconds. What is the magnitude of acceleration of the student?

Respuesta :

Answer:

The magnitude of acceleration of the student is 0.6 m/s²

Explanation:

Given that,

Initial velocity = 2.8 m/s

Final velocity = 4.7 m/s

Time = 3.4 sec

We need to calculate the magnitude of acceleration of the student

Using formula of acceleration

[tex]a=\dfrac{v_{f}-v_{i}}{t}[/tex]

Where, [tex]v_{f}[/tex] = final velocity

[tex]v_{f}[/tex] = final velocity

t = time

Put the value into the formula

[tex]a=\dfrac{4.7-2.8}{3.4}[/tex]

[tex]a=0.6\ m/s^2[/tex]

Hence, The magnitude of acceleration of the student is 0.6 m/s²
