The initial velocity is required so that the football just clears the goalpost crossbar that is 3.1 m above the ground is 13.7 m/s.
Projectile
Projectile is the curved motion experienced by an object which is thrown in space.
Given an angle (θ) = 35°, acceleration due to gravity (g) = 10 m/s². u is initial velocity
The maximum height (h) is:
- [tex]h=\frac{u^2sin^2\theta}{2g}[/tex]
For the ball to reach 3.1 m above the ground:
[tex]3.1=\frac{u^2sin^2(35)}{2(10)} \\\\u=13.7 \ m/s[/tex]
The initial velocity is required so that the football just clears the goalpost crossbar that is 3.1 m above the ground is 13.7 m/s.
