more specifically i am dealing with the values of kinetic energy when a pendulum swings at the bottom (velocity is recorded through a photogate at the bottom)
Assuming velocity recorded at the bottom is 1.9m/s (squared), and the mass of the object is 1kg, what is the kinetic energy for both values

Please help I have been out of school with a medical problem and my teacher has given me a paper on solving equations with the variable on both sides. I hvae no idea how to do it. Like for example a problem is: 0.4r-1.2=0.3r + 0.6. Which variable do I do first. Do I add 1.2 to both sides? Or do I subtract 0.6 from both sides? I dont understand this. Please help.
