Answer:
[tex]-9.06\:\mathrm{m/s^2}[/tex]
Explanation:
We can use the following kinematics equation to solve for acceleration:
[tex]v_f=v_f+at[/tex].
Solving for [tex]a[/tex]:
[tex]45=93+5.3a,\\-48=5.3a,\\a\approx \boxed{-9.06\mathrm{m/s^2}}[/tex]
*Note: Since acceleration is a vector quantity, it has both magnitude and direction. The negative sign implies that the acceleration is in the opposite direction of the racing dragster's movement.
