Which diagram shows the resulting wave when they cross at point X?
zvonat [6]

The resulting wave will have zero amplitude, thus it will form a straight line.

<h3>What is a crest?</h3>

A crest is an upward displacement of a progressive wave.

<h3>What is a trough?</h3>

A trough is a downward displacement of a progressive wave.

<h3>Superimposition of the two waves</h3>

When the two waves meet each other at point X, they will superimpose and cancel out since they have equal amplitude and are in opposite direction.

The resulting wave will have zero amplitude, thus it will form a straight line.

The roller-coaster car shown in fig. 6-41 (h1 = 45 m, h2 = 16 m, h3 = 26 m), is dragged up to point 1 where it is released from
kirill [66]

There are many ways to solve this but I prefer to use the energy method. Calculate the potential energy using the point then from Potential Energy convert to Kinetic Energy at each points.

PE = KE

From the given points (h1 = 45, h2 = 16, h<span>3  </span>= 26)

Let’s use the formula: 

v2= sqrt[2*Gravity*h1]  where the gravity is equal to 9.81m/s2

v3= sqrt[2*Gravity*(h1 - h3 )] where the gravity is equal to 9.81m/s2

v4= sqrt[2*Gravity*(h1 – h2)] where the gravity is equal to 9.81m/s2

Solve for v2

v2= sqrt[2*Gravity*h1]      

    = √2*9.81m/s2*45m

v2= 29.71m/s

v3= sqrt[2*Gravity*(h1 - h3 )   

    =√2*9.81m/s2*(45-26)

    =√2*9.81m/s2*19 

v3=19.31m/s

v4= sqrt[2*Gravity*(h1 – h2)]        

    =√2*9.81m/s2*(45-16)

    =√2*9.81m/s2*(29)

v4=23.85m/s
