A 15 kg mass is accelerated from rest with a force of 100 N. As it moves faster, friction and air resistance create an oppositively directed retarding force given by FR = A + Bv, where A = 25 N and B = 0.5 N/m/s. At what velocity does the acceleration equal to one half of the initial acceleration?

A

`25ms^(-1)`

B

`50m//s`

C

`75m//s`

D

`100m//s`
