A soccer player.

Jennings writes an example question on the board 'how high must a soccer player kick the ball if it is to go x metres with a horizontal speed of x metres per second. Gets an answer of ~250m high. Figures out the speed.

‘If this soccer player ever learns to kick straight, there’ll be some dead soccer players.’

‘if NASA wants a cheap way to put satellites into orbit, they’ll get this guy to kick it.’
