$(5$ pts$)7.$ A uniform solid disk with radius $R=0\mathrm{.}200m$ is mounted on a stationary horizontal frictionless axle at its center. The moment of inertia of the disk about the axle is $0\mathrm{.}240kg*m^2$A light rope is wrapped around the disk and a block with mass $m$ is suspended from the free end of the rope. The system is released from rest and the block descends with an acceleration of magnitude $2\mathrm{.}40\frac{m}{s^2}.$ While the block is descending, what is the tension in the rope?

$($a$)4\mathrm{.}90$ N

$($b$)9\mathrm{.}80$ N

$($c$)14\mathrm{.}4$ N

$($d$)19\mathrm{.}6$ N

$($e$)28\mathrm{.}8$ N

$($f$)$ none of the above answers
