Children playing in a playground on the flat roof of a city school lose their ball to the parking lot below. One of the teachers kicks the ball back up to the children as shown in thefigure below. The playground is 4.60 m above the parking lot, and the school building's vertical wall is h= 6.10 m high, forming a 1.50 m high railing around the playground. Theball is launched at an angle of 0 53.0 above the horizontal at a point d 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above thewall.

How much time does it take the ball to travel to the final x-position in terms of the angle? Using this result in the equationfor the final y-position, you should be able to write a quadratic equation for tangent of the angle.

Hello there, Was going through some example questions on my mechanics module and came across this question and have been struggling. The ball has a mass of 3kg, the vertical wall BC is 1000cm high - assume there is no friction. Due to gravity the ball goes down the path AB and then hits the ground at point D. How would I calculate the velocity of the ball at point B, and calculate the time the ball takes to reach point D and the distance CD.
