A 10 g particle is subjected to x 1 = 3 sin 20 t and x 2 = 4 sin ( 20 t + 2 π ) (SI). Select the correct statement(s).

At t = 0 : x = 4 . A = 9 + 16 = 5 . v ma x = 100 , a ma x = 2000 . E = 2 1 ( 0.01 ) ( 400 ) ( 25 ) = 50 J, so (D) is wrong.

A 10 g particle is subjected to $x_{1} = 3 sin 20 t$ and $x_{2} = 4 sin (20 t + \frac{π}{2})$ (SI). Select the correct statement(s).

Answer:

A, B, C

Solution:

At $t = 0$ : $x = 4$ . $A = 9 + 16 = 5$ . $v_{ma x} = 100$ , $a_{ma x} = 2000$ . $E = \frac{1}{2} (0.01) (400) (25) = 50$ J, so (D) is wrong.
