Understanding the Concepts

* Acceleration: The rate of change of velocity over time.

* Initial Velocity (v₀): The starting velocity, which is 0 m/s in this case.

* Final Velocity (v): The velocity after the time interval, which is 300 m/s.

* Time (t): The duration of the acceleration, which is 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. Solve:

a = 300 m/s / 0.5 s = 600 m/s²

Answer

The acceleration of the projectile is 600 m/s².
