\

Consider the velocity vector is $\"\"$ .

\

Where $\"\"$ and $\"\"$ are horizontal and vertical components.

\

The force is exerted at an angle of $\"\"$ above the horizontal.

\

The speed is $\"\"$ .

\

The angle of elevation is $\"\"$ .

\

Find the horizontal and vertical components of the velocity.

\

The horizontal component of the velocity is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

The vertical component of the velocity is $\"\"$ .

\

Substitute $\"\"$ and $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$ .

\

The horizontal component of the velocity is $\"\"$ ft/sec. \ \

\

The vertical component of the force is $\"\"$ ft/sec. \ \

\

$\"\"$

\

The horizontal component of the velocity is $\"\"$ ft/sec.

\

The vertical component of the force is $\"\"$ ft/sec. \ \
