Please answer all the questions and give the reasoning for each of the steps you make. I sometimes can't understand some people's work so please ensure that you show the reasoning for the work. This is a non-calculator question. Please solve it without the calculator. We can simplify the answer with the trig identity.
Two blocks are connected by a very light string passing over a
massless and frictionless pulley (Figure 1). Traveling at
constant speed, the 20.0 N block moves 80.0 cm to the right
and the 12.0 N block moves 80.0 cm downward.
