We'll use Newton's second law:
, where ΣF is the total force, m is the mass of the object, and a is the acceleration.
In the previous parts, you obtained the following equations using Newton's 2nd law and the constraint on the motion of the two blocks:
Solve these equations to find a1y.
Before you enter your answer, make sure it satisfies the special cases you already identified:
a1y=−g if m2=0 and
a1y=0 if m1=m2 and θ=π/2.
Also make sure that your answer has dimensions of acceleration.
Express a1y in terms of some or all of the variables m1, m2, θ, and g.
