A simple pendulum of length L, has a maximum angular displacement 0_max. At one point in its motion, its kinetic energy is K = 3 J and its potential energy is U = 4.2 J. When the pendulum's angular velocity is half its maximum value (e = e'_max/2), then its kinetic energy is: %3D O K= 0.8 J K = 0.45 J O K= 1 J O K=1.8 J

Question
A simple pendulum of length L, has a maximum angular displacement 0_max. At
one point in its motion, its kinetic energy is K = 3 J and its potential energy is U =
4.2 J. When the pendulum's angular velocity is half its maximum value (0' =
e'_max/2), then its kinetic energy is:
%3D
O K = 0.8 J
O K = 0.45 J
O K= 1 J
O K= 1.8 J
