An archer shoots an arrow at a 75.0 m distant target; the bull's-eye of the target is at same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull's-eye if its initial speed is 35.0 m/s? In this part of the problem, explicitly show how you follow the steps involved in solving projectile motion problems. (b) There is a large tree halfway between the archer and the target with an overhanging horizontal branch 3.50 m above the release height of the arrow. Will the arrow go over or under the branch?

A large cannon is fired from ground level over level ground at an angle of
300 above the horizontal. The muzzle speed is 980 m/s. Neglecting air
resistance, answer the following questions:
a) what is the maximum height that the projectile will reach?
b) how long till the projectile will hit the ground?
c) the projectile will travel what horizontal distance before striking the
ground?
A boy is standing from the top of a cliff 8 m from the ground
and he has a bow which is aimed 40 degrees from the horizontal. He
can release the bow with an initial velocity of 15 m/s. An
animal is below the cliff and is moving towards the boy at a
velocity of 5 m/s. For the bow to hit the animal, at what distance
D should the animal be when the bow is fired?
Imagine an archer preparing to fire an arrow. The archer aims the arrow directly ahead, that is to say, parallel with the ground. Bows are drawn to the corner of the mouth when fired. Let's say, for this particular archer, that puts the arrow 1.8 m (about 5.5 feet) above the ground. Assume that we have measured the initial speed of arrows fired by this archer with this bow and it is 100 m/s. (Ignore wind resistance) a) At what point during the arrow's flight will it be moving the fastest? (Be careful here, think about it. You don't need to do any calculations to figure this out.)
b) How long will it take for the arrow to hit the ground?c) How far will the arrow travel during this time period?
