Naruto!!!!

Some of the info was not needed.....heheh. It took me forever to make this problem because of a long time of research on my phone. First, you might have tried to figure out the static coefficient of friction, unfortunately this is not needed, it would be about .8 because 250= x303.8N which is half of gravity times Pains mass. All that needs to be done is use Newtons 2nd law= Force=mass acceleration and figure out how much the object decelerates. 250=62x x=4m/s. Then use an equation I found online ( which is hopefully correct ) v 2=u 2+2at. Final velocity 0= 2500-8m/s. This came out to be 2500m/s/8m/s=312.5 meters. If I'm wrong..... I'm really really sorry. Tell me what to change and if it sounds reasonable I'll try it.

Conversation of Energy:

Step 1: (mxvxv)/2=forcex displacement

Step 2: (62x50x50)/2=250xdisplacement

Step 3: Displacement= 310 meter

Finally someone watches naruto in here !!!!

v^2=u^2+ 2ax---------(i) F=ma-------------------(ii)

we have to find X from (i) and (ii).

i think you are wrong,your question say pain use the jutsu for gravity it means that his weight now is half than before his use the jutsu it menas his mass is half not 62 but 31, my calculating is 155 meter

The distance between point A and B is d =AB We know that Initial kinetic energy - Final kinetic energy = Fxd ,Vb=0 ==>Final kinetic energy = 1/2xMxVb²=0 d= (1/2 xMxVa²)/F d=0.5x62x50²/250 d=310meters

i think there is a mistake in the problem description. it was solved with pretty much basic equation: E=(m v^2)/2 and E=F s which when substituted still did not make any sense to the problem in the first place but still giving correct answer.
