Question

The equation of displacement of two waves are given as         3 y 1 10 t3sin  t3cos3t3sin5y  2  . Then what is the ratio of their amplitudes (a) 1:2 (b)2:1 (b) (c) 1:1 (d) none of these

Answer 1

Explanation:

A butcher throws a cut of beef on spring scales which oscillates about the equilibrium position with a period of T= 0.500 s. The amplitude of the vibration is A= 2.00 cm. Find:

a) frequency

b) the maximum acceleration

c) the maximum velocity

d) the acceleration when the displacement is 1.00 cm

e) the velocity when the displacement is 1.00 cm

f) the equation of motion as a function of time if the displacement is A at t= 0 sec. Hint: What is the phase angle if the x(t=0) = A?
