[QUOTE="TSny, post: 4514761, member: 229090"] OK for the normal force direction. For the direction of the acceleration, you should be able to see what it is without worrying about the forces. Use what you know about the acceleration of a particle moving in a circle with constant speed. [SIZE="1"][Although you don't need it for this question, the correct formula is F[SUB]net[/SUB] = ma, not F[SUB]net[/SUB] = mg. The acceleration of the particle is not g for this problem. F[SUB]net[/SUB] is the vector sum of all of the forces acting on the particle.][/SIZE] [/QUOTE]
