Answer 1

(C) 2.5 m/s^2

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
