Hi there, my question has to do with the velocity of a free falling object. I know that V=Vo + at, but if you dont know the time and the final velocity of the object, can you use another equation? I found this one"V^2=Vo^2 + 2(as)"-s being the distance travelled. Im trying to find the final velocity of an object that fell 134 meters from a bridge. Can somebody tell me please, if this is right, or point me in the right direction? Distance=134m Acceleration=9.8m.s^-2 So I did: V^2=Vo^2 + 2(as) = V^2=0^2 + 2(9.8 x 134) =V^2=2(1313.2 =V^2=2626.4 v=51.25 m per second also i need to know the time, so i did: t=(v-vo)/a t=(51.25)/9.8 t= 5.23 seconds im just not quite sure..also, is this equation for the average velocity or for the final velocity? thanks!!
