eric, a professional rooftop futbol player, kicked a 0.450 [kg] ball off a rooftop that is 81.0 [m] off the ground, at 15.0 [m/s] oriented 45.0° above his horizon. His pal, Joshua, caught the ball from a window at a distant building that is 46.0 [m] off the ground. Joshua then released the ball from this height and let the ball fall to the ground. A. What is the speed of the ball just before it reaches Joshua? B. What is the speed of the ball just before it reaches the ground?

I need help with this question: Emily throws a soccer ball out of her dorm window to Allison, who is waiting below to catch it. If Emily throws the ball at an angle of 30∘ below the horizontal with a speed of 14m/s, how far from the base of the dorm should Allison stand to catch the ball? Assume the vertical distance between where Emily releases the ball and Allison catches it is 8.0m. Express your answer with the appropriate units
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 the figure below. The playground is 6.00 m above the parking lot, and the school building's vertical wall is h = 7.10 m high, forming a 1.10 m high railing around the playground. The ball is launched at an angle of ? = 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 the wall.
