Firstly - What does an average adult dairy cow weigh?
Secondly - Is there any human being (a weight lifting athlete I presume) alive today that could lift this weight?
Thirdly - How much energy (J) would it take to lift tthe cow to160 cm (avg mans shoulder height) from the ground?
Fourth and finally the physics bit - Assuming it were possible to direct the strength of many people through that one athletes arm....how many people would it take to throw same said cow into orbit?

600 kg. That's about the world record for weight lifting from squat. Work done in raising 600 kg against 9.8 m/s^2 gravity acceleration by 1.6 meters is 9408 Joules. Tossing the cow into LEO would require 19 billion Joules, which would require 2 million of the world's strongest men. Maybe ten million of us average guys.

OK, I could lift a very small cow. I mean my niece has a little stuffed cow on her bed that I can throw across the room and I am not that strong.
Really, the guy who answered above me. Wow, you guys are smart. I am jealous.
