According to David Pescovitz over at Boing Boing, “Cow-tipping may be far more difficult than dumb jocks might lead you to believe.” He cites a recent study:
Ms (Tracy) Boechler, now a trainee forensics analyst for the Royal Canadian Mounted Corps, concluded in her initial report that a cow standing with its legs straight would require five people to exert the required force to bowl it over.A cow of 1.45 metres in height pushed at an angle of 23.4 degrees relative to the ground would require 2,910 Newtons of force, equivalent to 4.43 people, she wrote.
Of course, a “dumb jock” — like, oh, say, a wrestler — would know not to let the cow keep its legs straight and planted.
