The lemon trees will always be the same so they are the constants. The independent variable is the water amount because it is changing. The dependent variable is the amount of lemons because it is the variable being tested. (If we change the amount of water how many lemons will be produced?)
Answer:
<em>The car will travel 541.67 m</em>
Explanation:
<u>Uniform Acceleration </u>
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
The acceleration can be computed by solving for a:
And the distance traveled is calculated as follows:
The car travels during a time of t=30 s, and its speed changes from vo=50 Km/h to vf=80 Km/h.
Converting the speeds to m/s:
vo=50 Km/h * 1000/3600 = 13.89 m/s
vf=80 Km/h * 1000/3600 = 22.22 m/s
Both numbers are shown with a 2-decimal precision but they will be used with higher accuracy in further calculations.
Calculating the acceleration:
Now for the distance:
x = 541.67 m
The car will travel 541.67 m
Answer:
The speed of the wind is 70.7 units.
Explanation:
The velocity of the wind is equal to plane's velocity before the wind minus its velocity after the wind:
Now, the speed of the wind is the magnitude of :
which is the speed of the wind.
