helicopter flies an average velocity of 70 m/s2 for 10.0 seconds. What ios ther magnitude of the helicopter's displacement? answ
2 answers:
The uniform movement allows finding the results for the helicopter displacement during the 10 s is: 700 m
Kinematics studies the motion of bodies, finding relationships between the position, velocity and acceleration of the body, in the special case that the acceleration is zero, it is called uniform motion and is described by the equation
Where v is the average velocity, Ds is the displacement and t is the time
Δs = v t
They indicate that the average speed is 70 m / s and the travel time is t=10.0s
Let's calculate
Δs = 70 10.0
Δs = 700 m / s
In conclusion using the uniform movement we can find the results for the helicopter displacement is: 700 m

<u>Given the following data:</u>
- Velocity = 70 m/s
- Time = 10 seconds.
To find the magnitude of the helicopter's displacement:
Velocity can be defined as the rate of change in displacement (distance) with time.
Also, velocity is a vector quantity and as a result of this, it has both magnitude and direction.
Mathematically, velocity is given by the formula;
Making displacement the subject of formula, we have:
×
×
<em>Displacement </em><em>=</em><em> 700 meters.</em>
Therefore, the magnitude of the helicopter's displacement is 700 meters.

The Factors are Temperature and kinetic energy, the temperature is because the particles are going to move fast which means the particles in a solid container or in solid pattern they will actually vibrate and they will expand , when temperature increase, more kinetic energy between the particles .
examples is that in the steel when you heat a steel the particles inside it will vibrate then the particles speed up because the vibration increases, therefore the temperature increases so a a thermal expansion occurs that the vibration of the particles will take up more space so the steel bar expands slightly in all Direction if the temperature Falls the reverse happens and the material or steel contracts which means get smaller .
another example is the thermometer, the thermometer has a liquid inside it which is Mercury or alcohol this liquid expands when the temperature rises, the tube is made narrow so that a small increase in volume of the liquid produces a large movement along the tube.

answer
v = 4.2
set up an equation
we can use the formula for kinetic energy since we know mass and kinetic energy
K =
v =
values
K = 0.013 J
m = 1.5g = 0.0015 kg
plug in values
v =
v = 4.2
