On a frictionless incline at angle theta, the acceleration of any mass is:
Ag cos theta
Bg tan theta
Cg over theta
Dg sin theta
Answer & Solution
Correct answer: D. g sin theta
1. Only the weight component along the slope accelerates the object.
2. That component gives a equal to g sin theta.
3. It does not depend on mass.
