Projectile Motion

A ball is launched from the ground at 30 m/s at 45° above the horizontal. Ignore air resistance (g = 10 m/s²).

Scenario

A student kicks a ball on a football field. The ball leaves the foot at 30 m/s at 45° to the ground. Your goal is to predict where it lands and the maximum height it reaches.
