Thank you! That's what I told my student, but she seemed doubtful that an official question would have a misprint like that. Nice to hear that I'm not just missing something obvious.
I would actually imagine this is just a kinematics question - if you're only dealing with when it lands on the ground, it's easy to calculate the velocity up. And since you know initial velocity in the relevant direction, acceleration due to gravity, and final displacement (0), it should be...
Homework Statement
