A $20\ \text{kg}$ suitcase starts at rest and is then dragged forward across a horizontal frictionless floor by an angled force. The force is $50\ \text{N}$ and is exerted at $53^\circ$ above the horizontal. The force pulls the suitcase forward $5\ \text{meters}$ across the floor.

Which one of the following is closest to the suitcase's speed at the end of the $5\ \text{meters}$?

A

$3.9\ \text{m/s}$

B

$4.5\ \text{m/s}$

C

$5\ \text{m/s}$

D

$250\ \text{m/s}$
