Three objects with masses m1 = 36.3 kg, m2 = 17.7 kg, and m3 = 11.1 kg are hanging from ropes that are redirected over pulleys. What is the acceleration of m1? Negative numbers for downward, and positive numbers for upward, please.

Answer 1

are these masses somehow connected?

Answer 2

What is the magnitude of the net gravitational force on the m1=19kg mass in the figure?(Figure 1) Assume m2=m3=10kg.
