A 3 kg box rests on a horizontal surface. An external force 40 N is applied to the box, 30 degrees inclined from top. The box moves 5 meters to the right.

a) Find the works done by the external force and by the gravitational force.

b) the box starts its motion from the rest. Find the final speed of the box after it moves 5 meters to the right.
