Question

Find the vehicle's acceleration when its final velocity is measured as 45 m/s, the initial initial velocity was 0.0 m/s and the time elapsed was 8.5 seconds.

Answer 1

Acceleration (a)
`=5.29\ m\./s^2`

Explanation:

Given that

final velocity (v)
`=45\ m/s`

Initial velocity (u)
`=0\ m/s`

Time (t)
`=8.5\ seconds`

Then

`v=u+at\ ...................................... (1)`

Where
`a` is acceleration.

put the value in equation
`(1)`

`45=0+a*8.5\\a*8.5=45`

dividing
`8.5` both sides

`(a*8.5)/(8.5)=(45)/(8.5)\\\\a=(45)/(8.5)\\\\a=(450)/(85)\\\\a=5.29\ m/s^2`
