An object (mass 10.0 kg) slides upward on a slippery vertical wall. A force F of 60 N acts at an angle of 60 degrees (the force is 60 degrees South of the x+ axis, it's shown in a picture) Determine the normal force exerted on the object by the wall. Next, determine the object's acceleration. F=m*a F=m*g*sin(angle) a=g*sin(angle) Well I know that the equation for the y-dir would be 60cos60 which gives you 30 N. That is the normal force exerted by the wall. I can't visualize/understand this so if someone could explain this a bit better to me that would be great! I'm not sure of the other equations to use in this one.
