So I'm not exactly certain what you are asking for, but it sounds like question one can be answered using some basic physics formulas:

distance = velocity*time + acceleration*time^2/2
acceleration = force/mass

Start with how long the object will be in the air and use the above equations to solve for time in the vertical direction. Then solve for the horizontal force. I think that's what you are after anyway.

In your second question, are you asking how to make the object not rotate? You are setting the angular velocity specifically to make it rotate. Just don't do that. Also if you give it an infinite moment of inertia, no force will be strong enough to make it rotate.

thanks for your response.

For the 1st question, you got it right. I need sometime to figure out the implementation based on these formulae. I will take help of your player control example to get through it.

for the 2nd one, I want to rotate the sprite once during the flight path and was thinking of using the angular velocity of the box to get it. Now I am rethinking on it to achieve by other mechanism.

Thanks again.
