hi, i guess this is my first post. and it will be somewhat of a doozy. i hope someone out there can help. the problem goes as follows. a punter kicks a football such that it just clears a 10.0m high barrier 30.0m away. it continues another 10.0m to the ground. with what velocity (speed and angle) did the punter kick the ball? please help. this is horribly confusing to me.
