Answer:

[tex]a_{avg} = 180.85 m/s^{2}[/tex]

Given:

Initial velocity, u = 0 m/s

Final velocity, v = 34 m/s

Time interval, [tex]\Delta t = 0.188 s[/tex]

Solution:

Acceleration is the rate at which the velocity of an object changes.

Thus

Average acceleration, [tex]a_{avg} = \frac{\Delta v}{\Delta t}[/tex]

[tex]a_{avg} = \frac{v - u}{t - 0} = \frac{34 - 0}{0.188} = 180.85 m/s^{2}[/tex]
