Answer:
.
Assumptions:
- The object is dropped in a free fall.
- There's no air resistance.
- The downward acceleration due to gravity is
Explanation:
Consider the "SUVAT" equation
,
where
- is the final velocity,
- is the initial velocity,
- is the acceleration of the object, and
- is the change in the object's position.
For example, if the bottle needs to achieve a speed of by the time it reaches the ground,
- since the statement that the bottle is "dropped" implies a free fall.
- .
Apply the previous equation to find the minimum height, :
.
Replace the value and apply the formula to find the minimum height required to reach different final speeds.
Answer:
Range of projectile, R
For projection above ground surface, the range of the angle of projection with respect to horizontal direction, θ, is 0° ≤ θ ≤ 90° and the corresponding range of 2θ is 0° ≤ 2θ ≤ 180°.S
