A robot is moving across a flat surface. Its velocity vector is given by v

meters per second, where the x$-$component represents motion to the right and the

y$-$component represents motion upward.

$($a$)$ Find the component of the robot's velocity in the direction of the positive x $-$

axis. $($This is the scalar projection onto the x $-$axis$)$

$($b$)$ Find the component of the robot$$s velocity in the direction of the vector u $=$

$3,4>.($This requires finding the vector projection onto the vector u$)$
