Answer:
Acceleration (a) [tex]=5.29\ m\./s^2[/tex]
Step-by-step explanation:
Given that
final velocity (v) [tex]=45\ m/s[/tex]
Initial velocity (u) [tex]=0\ m/s[/tex]
Time (t) [tex]=8.5\ seconds[/tex]
Then
[tex]v=u+at\ ...................................... (1)[/tex]
Where [tex]a[/tex] is acceleration.
put the value in equation [tex](1)[/tex]
[tex]45=0+a\times8.5\\a\times8.5=45[/tex]
dividing [tex]8.5[/tex] both sides
[tex]\frac{a\times8.5}{8.5}=\frac{45}{8.5}\\\\a=\frac{45}{8.5}\\\\a=\frac{450}{85}\\\\a=5.29\ m/s^2[/tex]
