## What is the first time at which the kinetic energy is twice the potential energy?

At what time is the kinetic energy twice the potential energy first time? The motion of a particle is given by x(t) = (25cm) cos(12t), where t is in s. At what time is the kinetic energy twice the potential energy first time? PE = (1/2) kx^2 KE = (1/2) kA^2 – (1/2)kx^2 KE = … Read more
