Question answer for #3 Background:Kinematics is the study of motion. Kinetics is the study of what causes motion. If themotion has a constant acceleration, then some useful mathematical relationships can bederived:Constant Acceleration Equationsv = v; + atDefinition of WorkW = FAx1zatv} = v} + 2aAxAx = v;t +Definition of Kinetic EnergyKE = mv²%3DNewton's Second LawWork-Kinetic Energy TheoremW = AKEF = maObjective:Get acquainted with the constant acceleration equations, Newton's 2nd Law of motion, andWork and Energy. Learn to apply these equations to solve problems in 1-D.Procedure:Perform the indicated calculations. Use a coordinate system always; use a Free BodyDiagram (FBD) when necessary.1.
