Yeah. A 45 foot drop can be survived but it is gonna do a really nasty number on you.
Rolling will, hopefully, reduce the damage but you’re probably still gonna be in a world of hurt from that landing.
Humans can survive a fall from 50 feet but they have to be really lucky and land on something soft and properly landing will still mean your legs are, most likely, very much broken. And the broken legs are a certainty if you land on something hard like pavement.
