In an amusement park water slide, people slide down an essentially frictionless tube. the top of the slide is 3.2 m above the bottom where they exit the slide, moving horizontally, 1.2 m above a swimming pool. does the mass of the person make any difference?

No

Explanation:

When the person slides down, the change in gravitational potential energy is converted into kinetic energy, according to

where

m is the mass of the person

g is the acceleration of gravity

v is the final speed

is the change in heigth of the person

Here we have assumed that the initial speed is zero.

Re-arranging the equation,

and we see that this quantity does not depend on the mass of the person, so every person will have the same speed at the bottom of the slide, equal to:

i would say the answer is food.

hope this !

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
