A horizontal force, F1= 75N, ad a force, F2=15.4N acting at an angle of theta to the horizontal, are applied to a block of mass m= 2.

A horizontal force, F1= 75N, ad a force, F2=15.4N acting at an angle of theta to the horizontal, are applied to a block of mass m= 2.9kg. The coefficient of kinetic friction between the block and the surface is uk=0.2. The block is moving to the right.

what is noormal force?

what is the magnitude of accerlation of the blck, a in m/s2, if theta= 30.
