Abowling ball and a bag of potato chips are dropped at the same time from a tall tower on the moon. there is no air on the moon. what happens?

they both will hit the surface of moon at same time

Explanation:

When a bowling ball and potato chips are dropped at the same time on surface of moon

then during the motion above the surface of moon they both will have only force of gravity due to moon

so we have

now the we can say that the acceleration of object on this surface is given as

since this acceleration on both objects is independent of their mass

so we can say that they both will hit the surface of moon at same time

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

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.
