To win the game, a place kicker must kick a football from a point 21 m (22.9656 yd) from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 16 m/s at an angle of 55.3◦ from the horizontal. The acceleration of gravity is 9.8 m/s^2 By how much vertical distance does the ball clear the crossbar? Answer in units of m

In projectile horizontal distance is given by :

Putting all given values, we get :

Therefore, maximum height of football is 13.1 m.

Hence, this is the required solution.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
