A 1.50-kg penguin coasting along a frictionless surface of ice is rear-ended by another penguin and experiences a $+40.0 N$ force through a distance of $4.0 cm$ that increases its speed.

If the penguin's initial speed was 2.00 m/s, what would be its final speed?

A

$2.03 m/s$

B

$2.13 m/s$

C

$2.25 m/s$

D

$2.48 m/s$

E

$6.13 m/s$
