1.Range
2.Zero
3.vertical component of the initial velocity
4.Angle 1 and angle 2
explanation:
1 and angle 2 Angle 1 and angle 2 are complementary if the sum of both the angles is equal to 90 degrees (i.e. angle 1 + angle 2 = 90°) and thus, angle 1 and angle 2 are called complements of each other. In the figure given below, 60° + 30° = 90°.
5.45°
explanation:
45°Launch angles closer to 45 ° 45\degree 45° give longer maximum horizontal distance (range) if initial speed is the same (see figure 5 above).
6.Trajectory
explanation:
Projectile motion is a form of motion where an object moves in a parabolic path. The path followed by the object is called its trajectory.
7.The range of projectile
explanation:
range of projectile The horizontal displacement of the projectile is called the range of the projectile, and depends on the initial velocity of the object.
