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

A

`25 ms^(-1)`

B

`50 ms^(-1)`

C

`75 ms^(-1)`

D

`100 ms^(-1)`
