I need help with a certain type of projectile motion problem (dunno exactly what it's called), but here's an example (these problems don't include air resistance):
An archer lies on the ground and fires an arrow with an initial velocity of 112 ft/sec at 40 degrees. What is the maximum height that the arrow will reach?
Another problem that I have trouble with is the type of projectile motion that involves something going from a certain height to a lower height. Here's an example of this:
An archer stands on a hill so that the arrow in the bow is 20 m above the groundn and is aimed at an angle of 0 degrees relative to the ground. If the archer is trying to hit a target that is lying on the ground 118 m away, with what initial velocity must she launch her arrow?
Can anyone explain how to solve these problems? Thanks for the help
