A 20 g particle is subjected to two SHMs $x_{1} = 2 sin 10 t$ and $x_{2} = 4 sin (10 t + \frac{π}{3})$ ( $x$ in m, $t$ in s):

Options:(select one or more)

Answer:

A, B, C, D

Solution:

At $t = 0$ : $x = 4 sin 6 0^{\circ} = 23$ . $A^{2} = 4 + 16 + 2 (2) (4) cos 6 0^{\circ} = 28$ , $A = 27$ . $v_{ma x} = 10 A = 207$ . $a_{ma x} = 100 A = 2007$ . $E = \frac{1}{2} (0.02) (100) (28) = 28$ J.
