F=ma 

Velocity is Distance over time so Vf = 75/15 = 5m/s

Find acceleration V=Vo+at. plugging in the values you know, you get
0.33m/s^2

F=(2100)(0.33)=693N

PLEASE HELP! I don't get it at all! Speed is one thing; distance is another. Where is the arrow you shoot up at 50m/s when it ru

I got you b, V(final)^2=V(initial+2acceleration*displacement
So this turns to (0m/s)^2=(50m/s)^2+2(9.8)(d) so just flip it all around to isolate d so you get
-(50m/s)^2/2(9.8) = d so you get roughly 12.7555 meters up
