Answer:

The acceleration of the dragster is 13.33

Step-by-step explanation:

Given as :

The Final velocity of car = 65  m/s

The initial velocity of car = 125 m/s

The Time period for change of speed = 4.5 seconds

Now,

Acceleration is define as rate of change of velocity

So, Acceleration = \frac{v_2-v_1}{T}

Or,  Acceleration = \frac{125-65}{4.5}

Or, Acceleration = \frac{60}{4.5}

∴   Acceleration = 13.33  

Hence The acceleration of the dragster is 13.33   Answer
