Soccer players often fool around in practice with something called the "crossbar challenge" which is an attempt to kick the ball from the ground and have it hit the crossbar of the goal, which is 8.0 ft or 2.4 m above the ground. Use your physics skills to calculate an initial velocity (speed and angle) that could be used to hit the crossbar from a point where the ball is on the ground 11 m away from the goal. Neglect air friction for your calculations. (We'll assume that the air friction doesn't cause the ball to be deflected by more than half the diameter of the ball, so it still hits the bar.

Soccer players often fool around in practice with something called the "crossbar challenge"
which is an attempt to kick the ball from the ground and have it hit the crossbar of the goal,
which is 8.0 ft or 2.4 m above the ground.
Use your physics skills to calculate an initial velocity (speed and angle) that could be used
to hit the crossbar from a point where the ball is on the ground 11 m away from the goal.
Neglect air friction for your calculations. (We'll assume that the air friction doesn't cause
the ball to be deflected by more than half the diameter of the ball, so it still hits the bar.
