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.

Sweden and Norway are at war over who makes the best pickled herring. You are in charge of a Swedish artillery unit that is trying to shoot at some Norwegians located 1000 meters away at the same height as you are. If we neglect the friction of the air, the cannon ball follows a parabolic trajectory; as you certainly recall from prior courses, a cannon ball travels a distance L = V²sin(2a) 9 where V is the initial velocity, a is the angle of the cannon barrel, and g = 9.8 m/s² is the gravitational acceleration. You realize that you only have two options for how to shoot. Option (I) is to use 1 bag of gun powder, which produces an initial velocity of exactly V₁ = 105 m/s, and to try to set the angle to aI,nominal = 39 degree. Option (II) is to use 2 bags of gun powder, which produces exactly VII = 137 m/s, and to try to set the angle to aII,nominal = 15 degree. If you set the angles exactly to the nominal ones, compute the traveling distances. L₁ = LII = The problem is that the cannon…
