Understanding the Concepts

* Acceleration: The rate at which an object's velocity changes over time.

* Initial velocity (v₀): The velocity at the start of the time interval (0 m/s in this case).

* Final velocity (v): The velocity at the end of the time interval (300 m/s).

* Time (t): The duration of the change in velocity (0.5 seconds).

Formula

The formula for acceleration is:

acceleration (a) = (final velocity (v) - initial velocity (v₀)) / time (t)

Calculation

1. Plug in the values:

a = (300 m/s - 0 m/s) / 0.5 s

2. Simplify:

a = 300 m/s / 0.5 s

3. Calculate:

a = 600 m/s²

Answer: The acceleration of the projectile is 600 m/s².
