Answer:
The acceleration is found as:
a = 1000 km/h²
Step-by-step explanation:
Initial speed of the plane = 450 km/h
Final speed of the plane = 750 km/h
Time taken = 0.3 h
Acceleration can be defined as the change of speed of the object divided by the time taken to bring that change
Acceleration is given as:
![a=(v_f-v_i)/(t)](https://img.qammunity.org/2021/formulas/physics/middle-school/sv1h7ctq40d751v5c2zup3wfjruoca6wym.png)
where v(f) = 750 km/h , v(i) = 450 km/h , t = 0.3 h
Substitute the values in the equation of acceleration
![a= (750-450)/(0.3)\\a=(300)/(0.3)\\a=1000 km/h^2](https://img.qammunity.org/2021/formulas/physics/middle-school/5lg9f1azkmyj5o6qoq94xm007591yyvxeq.png)
This is the found result
