One guy drops an apple from a building and it lasts 5 seconds until it touches the ground. If each floor is 2.88 meters; calculate: The Final Speed of the apple (final speed when the apple touches the ground). From which floor the apple was dropped. Hehe :P

Actually there is enough information ._. Solve: Data (info): (On the text it says "drops" as a result of the initial speed is 0) t=5s Vo=0m/s Vf=? h=? Floor: ? g=9.81m/s² (Vo=initial speed, Vf=final speed, g=gravity, which on Earth is word widely taken as 9.81m/s²) Vf= Vo+gt Vf= 0+9.81(5) Vf= 49.05m/s h= (Vo+Vf)(t) 2 h= (0+49.05)(5) 2 h= (49.05)(5) 2 h= 245.25 2 h= 122.625m Floor= 122.625 2.88 Floor=42.578125 Its final speed is 49.05m/s. The apple was dropped on the floor 42. @Elvinar @Daddy there Daddy, ain't difficult c:
