Answer : It experience the acceleration is, [tex]7.5m/s^2[/tex]
Explanation :
By the 1st equation of motion,
[tex]v=u+at[/tex] ...........(1)
where,
v = final velocity = 85 m/s
u = initial velocity = 23 m/s
t = time = 8.3 s
a = acceleration = ?
Now put all the given values in the above equation 1, we get:
[tex]85m/s=23m/s+a\times (8.3s)[/tex]
[tex]a=7.5m/s^2[/tex]
Thus, it experience the acceleration is, [tex]7.5m/s^2[/tex]
