Yes, the Velocity (from your jump)minus the coefficient of gravity and frictional loss from air resistance.

Once you jump you are in free motion horizontally. Assuming no friction from the air you stay at a constant speed unless a force acts in the opposite direction to slow you down. Nothing "keeps you moving". Newtons 1st law ... a body in motion will stay in motion unless acted upon by a force.

Inertia. The force of your jump keeps you moving. The law of inertia states an object in motion tends to stay in motion unless acted upon by another force. Gravity will slow it down a bit, as will friction with the air, but what keeps you going (for a ways anyway) is INERTIA.

Well the force that you pushe off with your legs is the force that got you across the stream.. Actually its just the x-axis part of that force. The only forces that are acting on you in the air are gravity and the force of air friction. thats it.

When you apply an impulse( F*t) on the earth, the earth applies equal and opposite impulse ( - F*t)on you which produces momentum or velocity in your body. The horizontal velocity continues to move you horizontally till the vertical motion under gravity brings you down to the earth and the motion stops.

No force keeps you moving. Inertia keeps you moving. The only force is at the moment you jump. While you are in the air it is only inertia that keeps you moving.

this as to do with inertia an gravity
u jump inertia kicks in then in oder to land the force of gravity pulls u down

No. It is inertia, but that is not a force.
