SUMMARY

The field goal projectile problem involves calculating the time it takes for a ball kicked with an initial velocity of 27.0 m/s at an angle of 30.0° to reach the goal posts located 35 m away. By applying trigonometry, the horizontal component of the velocity is determined to be 23.1 m/s, while the vertical component is 13.5 m/s. The horizontal motion follows the formula d = vt, allowing for the calculation of time to reach the goal posts. The vertical motion is analyzed using kinematic equations to ensure the ball clears the 4.0 m height of the goal post.

A place kicker attempts a field goal, giving the ball an initial velocity of 27.0 m/s at an angle of 30.0° with the level field. The uprights are 35 m from the point at which the ball is kicked and the horizontal bar is 4.0 m from the ground.
At what time after the kick will the ball pass the goal posts?

Start with the initial velocity. Use trigonometry to find the vertical and horizontal components. The horizontal part is motion at constant speed, d = vt. The vertical motion is accelerated and you can use the velocity and distance formulas for that motion. Go as far as you can and you'll be eligible for more help!
