The formula for finding the kinetic evergy, E, of an object is given below, where m represents the mass and v represents the speed of the object

Step-by-step explanation:The formula is given as:We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables: Putting v to left side (convention), we finally have:

a)(x-2)^2+(y-1)^2=9
