Answer:
The stone thrown upward lands farther away from the building.
Step-by-step explanation:
Given that,
Angle = 30° above the horizontal
Speed = 18.0 m/s
Angle = 30° below the horizontal
Suppose, Which stone lands farther away from the building ?
We need to find which stone lands farther away from the building
Using formula of range
The horizontal velocity for the both stones is equal but the time will be different.
The time of stone thrown upward will be greater than that of downward.
Hence, The stone thrown upward lands farther away from the building.
