Answer:

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
is acceleration.

put the value in equation
(1)

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

dividing
8.5 both sides

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