Question

Displacement of a particle is x=3sin2t+4cos2t, amplitude and max. velocity will be:
a) 5,10
b) 3,2
c) 4,2
d) 3,8
Answer only if u knw, please!!!!!​

Answer 1

Answer:

Amplitude = 5, maxi V = 10

Explanation:

$\\ a = \sqrt{ {3}^{2} + {4}^{2} } \\ a = \sqrt{9 + 16} \\ a = \sqrt{25} \\ a = 5 \\ maximum \: v = aw \\ v = 5 \times 2 \\ v = 10 \\ coeficient \: of \: t \: is \: called \: frequancy(w)$

Answer 2

Answer:

Answer for the above equation is A). (5, 10)
