4) Monica starts running from rest to a velocity of 7 m/s. It takes her a total of 8 s. What is her acceleration?

HELP HELP PLZZZ PLZZZZ THIS IS LITERALLY MY LAST QUESTION

Respuesta :

Initial velocity (u) = 0 m/s

Final velocity (v) = 7 m/s

Time taken (t) = 8 s

Let the acceleration be a.

By using the equation,

a = (v-u)/t, we get

a = 7-0/8 = 7/8 = 0.875

Her acceleration is 0.875 m/s^2.
  • initial velocity=u=0m/s
  • Final velocity=v=7m/s
  • Time=t=8s

[tex]\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{7-0}{8}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{7}{8}[/tex]

[tex]\\ \sf\longmapsto Acceleration=0.8m/s^2[/tex]
