Answer:
Explanation:
You can ignore how high the window actually is, unless the calculator falls further. You just want to use the formula v_f = v_i + at Let em know if that doesn't help and I can work you through it.
To check the distance use y = v_i*t + .5at^2. Would just plug in 0*1.8 + .5(-9.8)1.8^2 = -15.876, so it doesn't fall more than 20.7 m so indeed, you don't have to worry about that.
Again, let me know if you need further help.
1- You should always have a question for your experiment.
2- You need to conduct background research. It helps to write down your sources so you can cite your references.
3- Propose a hypothesis (educated guess on what you believe the outcome of the experiment will be)
4- Design and perform an experiment to test your hypothesis (include independent and dependent variable)
5- Record observations and analyze what the data means.
6- Conclude whether you need to accept or reject your hypothesis, which accepting means your hypothesis was right and rejected is if it was wrong.
Do you mean in general or in a piece of paper?
Answer: e. 37
Explanation:
When two vectors are added, the maximum and minimum posible values, happen when both vectors are aligned each other.
If both vectors aim in the same direction, the maximum value is just the arithmetic sum of their lengths, in this case, 60.
If they aim in opposite direction, the resultant is the substraction of their magnitudes, which yields 20.
Any other posible value (depending on the angle between vectors, which can span from 0º to 180º) must be between those values.
So, the only choice that fits within this interval, is 37.
