# An object with a mass of 5 kg is on a surface with a kinetic friction coefficient of  2 . How much force is necessary to accelerate the object horizontally at 6 m/s^2?

$130 N$
To equalize the frictional force, we have to give force mumg=2×5×10=100N
Next,we have to give force 5×6=30N force for acceleration.
Hence total force is $100 + 30 = 130 N$
