Determine the acceleration and normal force of system below. Assume no friction, the mass equal to 10.0 kg and the angle equal to 60.0 degrees. Assume gravity equals 9.8 m/s/s.
The picture looks like a right triangle with a box sliding down it.
I am a 9th grader in conceptual physics, so the calculus is already provided for us. So if you could solve this without calculus, that would be great!

The normal force of the box is mg*cosTheta.
The force of gravity down the plane is mg*SinTheta
so the net force down the plane is
forcegravity-friction
because the friction is zero, then you don't have to worry about normal force in the motion.
Netforce=mass*acceleration
or acceleration= mgSinTheta/m= g*sinTheta
