    Slowest pitch in Baseball to reach catcher? 30 mph, thrown at 45-deg angle. Any slower and at any other angle hits the ground

        @neiltyson what if you only consider the component perpendicular to the coordinate based on a line between the pitcher and batter. Infinite.

        @neiltyson does that factor in the elevation of the mound?

        @neiltyson What if you factor in the lift gained from a ball thrown with significant backspin? Think upside down curveball spin.

        @neiltyson I calc'd this last week; 30.26mph but with mound/release height et al. Nice to be validated by DrNDT! #mathpic.twitter.com/ixOcdQYl

        @neiltyson does 45 degree angle = most distance for any object thrown, regardless of speed, mass, etc?

        @neiltyson Hubby begs to differ on angle. He says when he was in Army 47 degrees was lowest for artillery. Any smaller and shell hit dirt.

        @neiltyson that’s ignoring wind resistance. If I remember my physics labs correctly, the ideal angle is below 45°: http://www.physics.rutgers.edu/~zapolsky/381/aim.pdf …

        @neiltyson What would be the weakest hit homerun? Fenway has the shortest distance, at 302 feet. Not sure how high the wall is, though.

        @neiltyson Did you use 60.5 feet as the distance? The catcher is usually 3-4 feet behind the plate, in order to avoid contact with the bat.

        @neiltyson is that 30mph out of the pitchers hand or upon hitting the catchers glove?
