** I am confused on this being below the horizontal. Is that making Fy a negative? If so, would that then affect the calculation for normal force? A box (M = 4 kg) is resting on a frictionless horizontal surface. Then there is a 25 Newton force acting onit at an angle 35 degrees below the horizontal.1. Find the horizontal component of the force, Fx - I have Fcostheta so 25cos35 = 20.479 N2. Find the vertical component of the force, Fy - I don't know if this should be 25sin35 or 25sin(-35) 3. Find the normal force acting on the box - Fn = mg - Fy (but I do not understand if this is going to be a positive or negative Fy, obviously negative would make this mg + Fy)4. Find the acceleration of the box5. Find the distance it will travel in 3 seconds.
