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' = 0'_max/2), then its kinetic energy is: K = 1 J K = 0.45 J K = 1.8 J K = 0.8 J K = 0.75 J

Question
A simple pendulum of length L, has a
maximum angular displacement e_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' = O'_max/2), then
its kinetic energy is:
O K = 1 J
O K = 0.45 J
K = 1.8 J
K = 0.8 J
K = 0.75 J
