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: O K= 0.45 J O K= 0.8 J O K=1J O K-18J

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 Jand 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:
K= 0.45 J
K = 0.8 J
O K=1J
OK 18J
