Answer:
[tex]\huge\boxed{\sf a = 3.5 \ m/s^2}[/tex]
Explanation:
Initial velocity = [tex]V_i[/tex] = 0 m/s
Final velocity = [tex]V_f[/tex] = 16.1 m.s
Time = t = 4.5 seconds
Acceleration = a = ?
[tex]\displaystyle a = \frac{V_f-V_i}{t}[/tex]
Put the given data in the above formula.
[tex]\displaystyle a = \frac{16.1-0}{4.6} \\\\a = \frac{16.1}{4.6} \\\\a = 3.5 \ m/s^2\\\\\rule[225]{225}{2}[/tex]
