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

The object with the greater mass has a greater gravitational force and that determines what satellites orbit around it. An object with more mass will never orbit an object with less.
When a car maintains a velocity of exactly 65 mph, it's acceleration is zero.
<h3>What is acceleration?</h3>
The acceleration is time rate of change of velocity.
When the velocity is not changing with respect to time, it is said to be an object moving with constant velocity.
At constant velocity, there is no acceleration.
Thus, when a car maintains a velocity of exactly 65 mph, it's acceleration is zero.
