The potential energy $U$ of a particle is $U = 20 + (x - 4)^{2}$ J. The total mechanical energy is 36 J. Select the correct alternative(s):

Options:(select one or more)

Answer:

B, C, D

Solution:

$U - 20 = (x - 4)^{2}$ is a spring-type potential about $x = 4$ : SHM. $(x - 4)^{2} = 16$ at turning points: $A = 4$ . K.E. at $x = 2$ : $36 - (20 + 4) = 12$ J.
