ANSWER:
(C) 2.5 m/s^2
STEP-BY-STEP EXPLANATION:
Given:
m1 = 30 kg
m2 = 10 kg
The diagrams for each block would be as follows:
From the diagrams we establish the force balances:
We equate the tension to calculate the acceleration, like this:
The acceleration is 2.5 m/s^2, which means that the correct answer is (C) 2.5 m/s^2
