Kaya is riding her dirt bike eastward on a dirt road. She spots a pothole ahead. Kaya slows from 20.0 m/s to 6 m/s in 6.0 s. What is her acceleration?

Respuesta :

  • initial velocity=u=20m/s
  • Final velocity=v=6m/s
  • Time=t=6s

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

[tex]\\ \sf\longmapsto Acceleration=\dfrac{6-20}{6}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{-14}{6}[/tex]

[tex]\\ \sf\longmapsto Acceleration=-2.3m/s^2[/tex]
