Tennis ball, Time measuring device (cell phone) Hypothesis:
We will not have to write a hypothesis today, as I imagine you have not measured the maximum height of your throws before.

Procedure:
Please take a moment to design your procedure in the space below. Use a listed step by step format. (I don’t want to read paragraphs!) How will you set up your lab equipment? How will you collect your data? How will you record your data? What calculations will you need to make?

Things to include:
the initial conditions of your setup, a labeled diagram of your lab setup
any measurements and specifically how you will take them
some degree of repetition to increase the accuracy of your measurements
any calculations that you will need to come to a conclusion about how your independent and dependent variables are related.

f=ma newton

f=100x2.5=250n

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
