The potential energy of a 4 kg particle along the $x$ -axis is $U = 18 (x^{2} - 2 x)$ J. Its speed at $x = 1$ m is 3 m/s. Select the correct statement(s).

Options:(select one or more)

Answer:

A, C

Solution:

$U = 18 (x - 1)^{2} - 18$ , $k = 36$ , $ω = 3$ , $T = 2 π /3$ s. At $x = 1$ : $K = 18$ J, $U = - 18$ , so $E = 0$ . Turning points: $18 (x - 1)^{2} = 18$ , $x = 0$ and $2$ .
