1. The problem statement, all variables and given/known data A stone is thrown horizontally from a height of 10m above ground and moves with constant velocity of 5m/s. Calculate: a) the time it will take to hit the ground b) the distance traveled in the calculated time 2. Relevant equations Now for a i am using x = vot+1/2at2 but i just cannot get my head around it I understand that b will be velocity x time? 3. The attempt at a solution 10 = 0 x t +1/2 x 9.81 xt2 10 = ?????? I just have some kind of mental block going on, i've read my text books and websites but no luck.
