Answer:
y = -6.57 10⁻³ m
Explanation:
The movement of water is an oscillation in the vertical direction that can be approximated as a simple harmonic movement
y = A cos (wt)
where the amplitude is A = 0.75 m and the angular velocity is related to the frequency
w = 2π f
w = 2π 1.25
w = 7.85 rad / s
we substitute
y = 0.75 cos (7.85 t)
we look for the amplitude for a time of t = 2.20 s, remember that the angles are in radians
y = 0.75 cos (7.85 2.20)
y = -0.00657 m
y = -6.57 10⁻³ m
Answer:
90 J
Explanation:
Change in potential energy when the spring is stretched
ΔU = ∫[(F) dx]................... Equation 1
Where F = 40x-6x²
Substitute into equation 1
ΔU = ∫[40x-6x²]
ΔU = [40x²/2 + 6x³/3 +C]
ΔU = [20x²+2x³ +C]
If the spring is stretch from x = 0m to x = 2m
ΔU = [20×2²+2×2³+C]-[20×0²+2×0³+C]
ΔU = [80+16+C]-[C]
ΔU = 90 J.
Hence the change in potential energy of the spring = 90 J
