Understanding Accelerations Practice Test

A box is placed on a 30o frictionless incline. What is the acceleration of the box as it slides down the incline?

Three blocks (in left-to-right order: block A, block B, block C) are pushed along a frictionless horizontal surface by a 50N force to the right, which acts on block A.

If the masses of the blocks are given by , , and , which of the following best describes the relationship between the accelerations of the blocks?
