Answer:
u₂ = 3.7 m/s
Explanation:
Here, we use the law of conservation of momentum, as follows:

where,
m₁ = mass of the car = 1250 kg
m₂ = mass of the truck = 2020 kg
u₁ = initial speed of the car before collision = 17.4 m/s
u₂ = initial speed of the tuck before collision = ?
v₁ = final speed of the car after collision = 6.7 m/s
v₂ = final speed of the truck after collision = 10.3 m/s
Therefore,

<u>u₂ = 3.7 m/s</u>
Lightly press the brake until the apex is reached. after the curve gently apply some acceleration
Answer:

Explanation:
Energy and mass are related by the famous equation developed by Albert Einstein:

where m = mass and c = speed of light
This equation explains that an object with very small mass can produce a large amount of energy in reactions such as a nuclear reaction.
Hence, the energy produced by the explosion of a Plutonium bomb containing 3.6 grams of matter is:

E = 
Well, there are different ways you can represent the motion
of the pendulum on a graph. For example, the graph could
show the pendulum's displacement, total distance, position,
speed, velocity, or acceleration against time. Your question
doesn't specify which quantity the graphs show, so it's pretty
tough to describe their similarities and differences, since these
could be different depending on the quantity being graphed.
I have decided to make it simple, and assume that the graph shows
the distance away from the center against time, with positive and
negative values to represent whether its position is to the left or right
of the center. And now I shall proceed to answer the question that
I just invented.
In both cases, the graph would be a "sine" wave. That is, it would be
the graph of the equation
Y = A · sin(B · time) .
' A ' is the amplitude of the wave.
' B ' is some number that depends on the frequency of the swing . . .
how often the pendulum completes one full swing.
The two graphs would have different amplitudes, so the number 'A'
would be different. It would be 5 for the first graph and 10 on the 2nd one.
But the number 'B' would be the same for both graphs, because
when she pulled it farther and let it go, it would make bigger swings,
but they would not happen any faster or slower than the small swings.
In the space of, say one minute, the pendulum would make the same
number of swings both times. That number would only depend on the
length of the string, but not on how far you pull it sideways before you
let it go.
The strength of the electromagnet depends on how many coils you wrap round and how high the voltage is. ... N Increasing the number of coils, which adds more field lines and makes the electromagnet stronger. This is the magnetic field around a piece of wire, compared to a magnetic field on a loop or solenoid it is weak.
