There is no wind. The fox curls into a tight ball as soon as he leaves the cliff edge. There is a deep pool of water extending between 50 meters from the cliff and 100 meters from the cliff.
Does the fox land in the water?

Should travel about 54 meters. Right into it :)

Well, just look at this from two different directions. First you need to know how long he is in the air. The only thing pulling him down is gravity which does it with an acceleration of about 10 m/s/s. So, we take the equation
dY=V0*T + (A*T^2)/2
dY = 100 (the height)
V0 = 0 (the initial velocity, he didnt jump up)
A = ~10 (gravity)
Solve for T. I will let you do that. Now, you know how long he is in the air. Pretend he is still running forward even while in mid-air. 12 m/s * T s = distance traveled before hitting the ground. If 12*T is greater then 50 but less then 100, he lands in the pool. otherwise, he does not. Good luck!

From own journey this is sturdy. I ran a 14 whilst i became 12 and because then I even have performed soccer for my severe college and went with the aid of an entire season of indoor music. enable me aid you understand now i will hit severe 11s and that i atribute all of it to confusing paintings. you have a thirteen 2d a hundred meter suitable now yet once you do no longer run and paintings at it thats is as sturdy as you will get. So get entangled in music in case you haven't any longer already and paintings confusing and that element will drop much greater. so some distance as how briskly a woman could run her a hundred meter I dont think of there's a time a woman could run. it is going to be distinctive for each guy or woman and each style of runner. yet whilst case in point you had to be a sprinter you will possibly choose to run in numerous low sixteen - low 17. in case you are able to run it quicker than that super yet that element is sufficient for a coach to paintings with sufficient so as that by making use of the time senior 300 and sixty 5 days hits in highschool you will possibly be able to nicely be a aggressive sprinter. in case you're middle distance or long distance runner #one million you in all possibility won't run a a hundred meter yet once you probably did do no longer anticipate to be as quickly as a sprinter. yet there exceptions to that like one youngster on my team. He runs six hundred meter races and up yet he can run as quickly as lots of the sprinters on our team. in case you pick to run quicker connect your faculties music team and spot the way it is going. sturdy success!!!

At 12 m/s it would take him about 4.17 seconds to travel the 50 metres, does he fall for 4.17 seconds? At an acceleration of 9.8m/s/s he would reach freefall (about 55m/s) in about 3 seconds. He would have fallen nearly 60 metres; he would fall another 55 metres in the next second, and would hit the ground well within the 4 seconds required. So, no, he wouldn't make it.

He falls straight down to the point in which he launched. You said it was a "perfectly-vertical cliff." I'd love to see a fox run 27 mph straight up a vertical "cliff."
