1. The problem statement, all variables and given/known data A body is suspended vertically from an ideal spring of spring constant 3.5 N/m. The spring is initially in its relaxed position. The body is then released and oscillates about its equilibrium position. The motion is described by the following equation. y = (4.5 cm) sin [(0.62 rad/s)t] What is the maximum kinetic energy of the body? [answer in mj) 2. Relevant equations Kmax=.5kA^2 3. The attempt at a solution .5(3.5)(.045)^2=.003543 J but the answer must be in mj. So, 3.543x10^-9 BUT computer did not accept the answer as a correct one... Could anyone help me please? Thanks!
