A 3.5 kg box is pushed along a horizontal floor by a force F of magnitude 15N at an angle of 40degrees below the horizontal. The coefficient of kinetic friction is 0.25. Calculate the magnitude of the frictional force on the block from the floor and the acceleration of the block.(adsbygoogle = window.adsbygoogle || []).push({});

I dont really know where to start.

Can anyone Help?
