This research work study the motion of a
projectile without air resistance using vector-valued
function. In this work, we combined the factors that
affect the path of a trajectory to determine how a pilot
can jump off from an aircraft into a river which is
located at a known distance without falling on the
ground in case there is a failure in the parachute. Based
on our study of the problem statement, we established a
theorem which states that at every maximum point
(time) of a projectile (ignoring air resistance), the
tangential component of acceleration is equal to zero
and the normal component of acceleration is equal to
gravity.
