<span>Displacement of the oscillator can be expressed in the mathematical form as:
x(t) = A*cos (ωt + δ),
therefore acceleration would be represented as => a = ¨x = â’ω^2*A*cos (ωt + δ),
the maximum acceleration will happen when the cosine is -1.
Hence, maximum acceleration => a-max = A*ω^2
The force associated with acceleration is F = ma.
Therefore maximum amplitude is
A = F / (m*ω^2)
= F / (4Ď€^2 * m * f^2) where f is the frequency of oscillation.
putting values in above equation we ge:
A = 50000 / 4Ď€^2 * 10^â’4 Ă— (10^6)^2
= 1.25 * 10^â’5
hence 1.25 * 10^-5 m/s^2</span>
Answer: Once upon a time there was a world without gravity. Billy Bob was sitting at home and his dad went to get some milk. But when he stepped out he floated away. Billy Bob never saw his dad again. The end.
Explanation:
Speed=frequency*wavelength
Given
frequency=1200\ Hz
and
wavelength=0.300\ m
we get:
speed=1200\ Hz*0.300\ m=360\ m/s
Where are the statements? You forgot to attach them lol
Explanation:
Given that,
Length of the cable is 19.6 m, l = 19.6 m
Let us assume that the angle with vertical rotating pole is 63 degrees.
The total mass of a chair and its occupant is 250 kg.
(a) Let T is the tension in the cable attached to the chair. So,
(b) The centripetal acceleration acts on it such that,
Hence, this is the required solution.
