Understanding Maximum Height in Projectile Motion
In projectile motion, the maximum height (h) attained by an object is influenced by its initial velocity (u), the angle of projection (θ), and the acceleration due to gravity (g). The relationship between these variables can be derived using kinematic equations.
Deriving the Formula
1. Components of Initial Velocity
- The initial velocity can be split into horizontal (u cos θ) and vertical (u sin θ) components.
2. Time to Reach Maximum Height
- At maximum height, the vertical component of velocity becomes zero.
- Using the formula:
\[
v_y = u_y - g t
\]
Setting \( v_y = 0 \):
\[
0 = u \sin \theta - g t_{\text{max}}
\]
Solving for \( t_{\text{max}} \):
\[
t_{\text{max}} = \frac{u \sin \theta}{g}
\]
3. Maximum Height
- The maximum height (h) can be calculated using:
\[
h = u_y t_{\text{max}} - \frac{1}{2} g t_{\text{max}}^2
\]
Substituting \( t_{\text{max}} \):
\[
h = (u \sin \theta) \left(\frac{u \sin \theta}{g}\right) - \frac{1}{2} g \left(\frac{u \sin \theta}{g}\right)^2
\]
Simplifying gives:
\[
h = \frac{u^2 \sin^2 \theta}{2g}
\]
4. Finding Velocity of Projection
- Rearranging to find u:
\[
u^2 = 2gh \frac{1}{\sin^2 \theta}
\]
Hence,
\[
u = \sqrt{\frac{2gh}{\sin^2 \theta}} = \frac{\sqrt{2gh}}{\sin \theta}
\]
5. Final Expression
- The velocity of projection (u) can be expressed as:
\[
u = \frac{2gX}{\sin \theta}
\]
Conclusion
Thus, the velocity of projection necessary to achieve a maximum height (h) under the gravitational field of Earth can be derived as \( u = \frac{2gX}{\sin \theta} \), demonstrating the relationship between height, projection angle, and gravitational acceleration.
