Resolve or break the motion into horizontal and vertical components along the x- and y-axes. These axes are perpendicular, so
A
x
=
A cos
θ
and
A
y
=
A sin
θ
are used. The magnitude of the components of displacement
s
along these axes are
x
and
y
.
The magnitudes of the components of the velocity
v
are
v
x
=
v
cos
θ
and
v
y
=
v
sin
θ
,
where
v
is the magnitude of the velocity and
θ
is its direction, as shown in Figure 2. Initial values are denoted with a subscript 0, as usual.
Step 2. Treat the motion as two independent one-dimensional motions, one horizontal and the other vertical. The kinematic equations for horizontal and vertical motion take the following forms:
