Question: 1. A cannon res a projectile with an initial velocity of 30 m/s. Calculate the launch angle () above the horizontal if the vertical range

1. A cannon ﬁres a projectile with an initial velocity of 30 m/s. Calculate the launch angle (θ) above the horizontal if the vertical range is 15 meters.

2. Given the initial velocity (30 m/s) and launch angle from previous Question , calculate the horizontal range (maximum horizontal distance traveled) of the projectile.
