when abody is thrown upward,how many forces act on it?what is the role of the force with which the body has been thrown upward?
After a body is thrown upwards, you have gravity pulling it down and friction slowing it.
In most cases, when a body is at rest, there are two forces acting on it: the force of gravity pulling downward and the normal force pushing upward. These forces are equal and opposite, resulting in a balanced or net force of zero.
2, gravity & buoyancy.
No matter how the ball is thrown (spin, slider, etc.) the two main forces acting on a ball thrown are the force along the direction of the flight of the ball and the force of gravity that always pulls it towards the center of the earth.

When many forces acting on the body then in the line of action of resultant forces of all applied forces, acceleration is produced.And if the value of resultant force increase with time then acceleration.a = FNET/mass of bodyOR,If change of momentum of body increases with respect to time then acceleration increase.a = ( mv-mu )/ twhere:-a=acceleration of bodym=mass of bodyu=initial velocity of bodyv=final velocity of bodyt=time taken to increase the velocity of body from u to v
ALOT!!
Once it is in the air, the main forces are gravity, and air resistance.
2 is the answer

Exactly one . . . the gravitational force.
Your answer is ARROW!
No matter how the ball is thrown (spin, slider, etc.) the two main forces acting on a ball thrown are the force along the direction of the flight of the ball and the force of gravity that always pulls it towards the center of the earth.

Trebuchets aren't thrown. It is a catapult. It launches things. Many different things.
Way more than Asomugha got thrown at.
