B. Variable
C. Control
D. Hypothesis
b. What speed must the student leave the ground with to reach that height?
The hang time of the student is 0.64 seconds, and he must leave the ground with a speed of 3.13 m/s
Why?
To solve the problem, we must consider the vertical height reached by the student as max height.
We can use the following equations to solve the problem:
Initial speed calculations:
At max height, the speed tends to zero.
So, calculating, we have:
Hang time calculations:
We must remember that the total hang time is equal to the time going up plus the time going down, and both of them are equal,so, calculating the time going down, we have have:
Then, for the total hang time, we have:
Have a nice day!
Answer:
6Ω
Explanation:
The 6Ω resistor and the 3Ω resistor are in parallel.
R = 1 / (1/6 + 1/3)
R = 1 / (1/6 + 2/6)
R = 1 / (3/6)
R = 6/3
R = 2
The 8Ω resistor and the other 8Ω resistor are also in parallel.
R = 1 / (1/8 + 1/8)
R = 1 / (2/8)
R = 8/2
R = 4
This 4Ω resistance is in series with the 4Ω resistor.
R = 4 + 4
R = 8
The 2Ω resistor and the 6Ω resistor are also in series.
R = 2 + 6
R = 8
These two 8Ω resistances are in parallel.
R = 1 / (1/8 + 1/8)
R = 1 / (2/8)
R = 8/2
R = 4
Finally, this 4Ω resistance is in series with the 2Ω resistance we found earlier.
R = 4 + 2
R = 6
The total equivalent resistance is 6Ω.
