Determine a formula for the acceleration of the system in terms of mA, mB, θ, and g. Ignore the mass of the cord and pulley. Express your answer in terms of the variables mA, mB, θ, and g.

Explanation:

Given two mass on an incline code and and an angle of inclination . . Assume that is the weight being pulled up and the hanging weight.

-The equations of motion from Newton's Second Law are:

where a is the acceleration.

#Substituting for (tension) gives:

#and solving for

which is the system's acceleration.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
