You bet, it would be like a sling shot. It would sling through the air like piece of shot and cause a lot of damage even at 30. Hope that helps some!
30mph
A lot, lot worse than a 30 mph crash, as the crashing object will take longer to stop.
K= 1/2mv2 eg. 10kg, 30mph convert speed into meter/second 30mph = 13.4112m/s so, half of mass = 5 multiplied by the velocity squared 0.5 x 10 x (13.41122) =899.3014272 joule
