How long does a ship take to cross the pacific?

When two cars collide with each other then the momentum is same before collision and after collision but energy is changed after collision in form of heat and sound.

We know this collision is inelastic collision.

In Inelastic collision, when two objects collide with each other then the momentum is conserved but kinetic energy is not conserved.

Suppose high tide is at midnight, the water level at midnight is 3 m, and the water level at low tide is 0.5 m. Assuming the nex

aev [14]

We have that the time, to the nearest minute, when the water level is at 1.125 m for the second time after midnight is

$t=10.0hours$

From the Question we are told that

Maximum height $h_{max}=3m$

Minimum height $H_{min}=0.5m$

Time for next high tide will occur $T=12 hours =>720 min$

Generally Average Height

$h_{avg}=\frac{3+0.5}{2}\\\\h_{avg}=1.75$

Therefore determine Amplitude to be

$A=h_{max}=j_{avg}\\\\A=3-1.75\\\\A=1.25$

Generally, the equation for Time is mathematically given by

At t=0

$h(x)=Acos(Bx)+h_{avg}$

Where

$B=\frac{2\pi}{P}\\\\B=\frac{2\pi}{720}\\\\B=8.73*10^{-3}$

Therefore

$h(t)=Acos8.73*10^{-3}(t)+h_{avg}$

Hence the Time at $T=1.125$ is

$1.125(t)=1.25cos(8.73*10^{-3})(t)+1.75$

$-0.1249t=1.75$

$t=10.0hours$
