[QUOTE="Mei_797, post: 4893014, member: 528127"] [I]I am not good at typing out formulas and equations on the internet, so I took pictures of what I did instead.[/I] [I]I hope that's not too informal.[/I] [B] 1. Homework Statement [/B] A rock is tossed straight up with a velocity of 19 m/s. When it returns it fell into a 10 m deep hole. [B]Q[/B]: What is the rock's velocity as it hits the bottom of the hole? [h2]Homework Equations[/h2] [ATTACH=full]173567[/ATTACH] [h2]The Attempt at a Solution[/h2] [ATTACH=full]173568[/ATTACH] So in the end I figure out that I am suppose to plug 19 m/s as my initial velocity, but I don't get why. If the rock is tossed straight up should it not means that the initial velocity = 0 because initially the rock is at rest?[/B] [/QUOTE]
