What is the acceleration of a car that goes from 5m/s to 95m/s in 10s?
A. 45m/s^2
B. 100m/s^2
C. -9m/s^2
D. 9m/s^2

Respuesta :

  • Initial velocity=u=5m/s
  • Final velocity=95m/s=v
  • Time=t=10s

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

[tex]\\ \tt\longmapsto Acceleration=\dfrac{95-5}{10}[/tex]

[tex]\\ \tt\longmapsto Acceleration=\dfrac{90}{10}[/tex]

[tex]\\ \tt\longmapsto Acceleration=9m/s^2[/tex]
