Question #1528

The displacement of a block attached to a horizontal spring whose spring constant is 6 N/m is given by

x = 0.4 \cos(4.1 t - 0.8) m.

What is the earliest time (t > 0) when the kinetic energy equals one-half the potential energy?

x = 0.4 \cos(4.1 t - 0.8) m.

What is the earliest time (t > 0) when the kinetic energy equals one-half the potential energy?
