'Wired' for Tension

APPH12-8KXNYL

A $5.0\text{ kg}$ metal sphere is suspended by massless wire of length $2.0\text{ m}$. The sphere is set into a swinging motion by being pulled to the side and released. At the bottom of its swing, the sphere is moving at $3.0\text{ m/s}$. What is the tension in the wire when the sphere is at this lowest position?

A

$27\text{ N}$

B

$28\text{ N}$

C

$54\text{ N}$

D

$72\text{ N}$
