the range before it reaches the farthest distance? After reaching the
maximum range?

Answers & Comments
Answer:
1.75°
2.they will cover the same range
3.75°
4.increasing the launch angle increases the maximum height.
5.it shows different paths for the same object being launched at the same initial velocity and different launch angles.
6.Higher launch angles have higher maximum height
2. The range or the maximum horizontal distance travelled by
the clay at 30º and 60º angles is the same.
The range or the maximum horizontal distance travelled by
the clay at 15º and 75º angles is the same.
Note that complementary angles (90−θ) produces the same
range since:
3. 75º
45º & highest at 60º angle. (note: given equal initial velocity)
5. The range before it reaches the farthest distance (when
launched at 45º) increases as the angle of release increases.
After reaching the maximum range (when launched at 45º), as
the angle of release increases (beyond 45º) the range of a
projectile decreases until it becomes 0 at 90º
can be reach by a projectile also increases.
