Expert Answer

Step 1

Projectile motion: Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity.

Step 2

Initial velocity

The initial velocity can be expressed as x components and y components:

u=u-cos
u, usine
Where u stands for initial velocity magnitude and 0 refers to projectile angle.

Time of Flight (T)

The time of flight of a projectile motion is the time from when the object is projected to the time it reaches the surface. T ...
