Question

A car increases its velocity from zero to 97 km/h in 8.4 s. What is its acceleration?

Answer 1

`a=(v-u)/(t)`

`v=`final velocity =97km/h(change to m/s) =26.9m/s NEVER FORGET TO DO THAT BECAUSE TIME IS GIVEN IN SECONDS

`u=`initial velocity 0 m/s

`t=`time 8.4s

`a=(26.9-0)/(8.4)`

`a=`
`3.2m/2^(2)`
