anonymous · Answer

to find the acceleration in a given direction ,u need force acting on the object in THAT direction ,,,
Find out the force acting on the block down the incline  ,,,,i mean the force vector that is parralel to the direction of motion of the block(slant)
this force is nothing but the component of the Gravitational force acting on the object along the incline,,,,Fsintheta

what is FI ? additional force? or just the component of Fg(20n)
