Practice: Water pours from a spout at the end of a gutter with a speed of 3.5 m/s, where the spout is angled 45° downwards. The magnitude of the water’s velocity when it hits the ground is 14 m/s. How high is the spout from the ground?

Concept #1: Solving Downward Launch Problems
Practice: Water pours from a spout at the end of a gutter with a speed of 3.5 m/s, where the spout is angled 45° downwards. The magnitude of the water’s velocity when it hits the ground is 14 m/s. How high is the spout from the ground?
Example #1: A cannon mounted on a tall fort fires a cannonball with 73 m/s at 49° below the horizontal. If the fort is 300m above the ground, what horizontal distance does the cannonball travel before hitting the ground?
