Q1. A street lamp weight 164N. It is supported equally by two wires that form an angle of 129 degrees with each other. What is the tension of each of these wires?

If the angle of each of these wires is reduced to 79 degrees, what new force does each wire exert?

Q2. A 95 kg spacewalking astronaut pushes off a 625 kg satellite; exerting a 87 N force for the 0.440 s it takes him to straighten his arms.

How far apart are the astronaut and the satellite after 1.30 minute?
