A car starts from rest and accelerates uniformly over a time of 6.92 seconds for a distance of 163 m. Determine the acceleration of the car. (Round to one decimal place.)


(okay but can someone actually help because if I don't pass this ima fail physics)

Respuesta :

  • t=6.92s
  • s=163m
  • u=0m/s

[tex]\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2[/tex]

[tex]\\ \sf\longmapsto 163=0(6.92)+\dfrac{1}{2}a(6.92)[/tex]

[tex]\\ \sf\longmapsto 163=3.46a[/tex]

[tex]\\ \sf\longmapsto a=\dfrac{163}{3.46}[/tex]

[tex]\\ \sf\longmapsto a=47.1m/s^2[/tex]
