A 0.1000-kg marble is fired by a boy from a slingshot at point A, at a height of 1.500 m from the ground. It hits a frictionless inclined concrete wall at point B, which is 30.0 m away from the boy. After hitting the wall, the marble rebounds with a velocity, VB, directed 140° from the horizontal as shown. The ball finally hits point C on the frictionless floor. The velocity of firing, VA, is 20.0 m/s, directed 45.0° with the horizontal. VA 20 m/s = A 45° 1.5 m C! VB 60° B o = 140°

A playground is on the flat roof of a city school, h, - 5.30 m above the street below (see figure). The vertical wall of the building is h-7.80 m high, to form a 15-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 0-53.0° above the horizontal at a point d-24.0 m from the base of the building wall.

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 5.60 m above the parking lot, and the school building's vertical wall is h = 6.90 m high, forming a 1.30 m Ngh railing around the playground. The ball 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 the wall.
