Question

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)

Answer 1

• t=6.92s
• s=163m
• u=0m/s

`\\ \sf\longmapsto s=ut+(1)/(2)at^2`

`\\ \sf\longmapsto 163=0(6.92)+(1)/(2)a(6.92)`

`\\ \sf\longmapsto 163=3.46a`

`\\ \sf\longmapsto a=(163)/(3.46)`

`\\ \sf\longmapsto a=47.1m/s^2`
