Annie ran and then if we know how long it took her to fall.. about .5 seconds we can determine her velocity while running and her velocity while falling. While she is running, we can use the equation v= d/t to determine her velocity, so v = 100//10s she runs at a speed of 10m/s which is pretty fast ( and I'm just guessing). Also is we know she fell with an acceleration of 9.81m/s2 and it took .5 seconds for her to hit the ground. We can determine her velocity while falling. a= v/t and rearrange it to v= at so (9.81m/s2)(.5s) which is about 5 m/s... ouch she falls fast and hard!
Well Annie's falls are only part of how entertaining she is to watch aside from her amazing skills!
