A single-scoop ice cream cone is a composite body made from a single scoop of ice cream placed into a cone. (Figure 2) Assume that the scoop of ice cream is a sphere with radius r=1.58 in. that is placed into a 4.00 in. tall cone. The interior height of the cone is 3.60 in. The cone has an exterior radius of 1.25 in. and an interior radius of 1.10 in. The scoop of ice cream sits on the cone's interior radius and extends into the cone some distance. Find the "z bar" centroid for the cone (the scoop of ice cream and the cone).

Solution: The projectile motion equations: x = x₁ + (vo cos 0) t y = yo + (vo sin 0o) t - 1/2gt² Call the starting point (xo, yo) = (0,0). To find (x, y) for the ending point, use triangle trig on the hill angled at 20°: x = d cos 20° = .940d and y = d sin 20° = .342d Plug in: .940d = (vo coso) t (Eqn. 1) .342d = (vo sin 0o) tgt² (Eqn. 2) The variable t is not mentioned in the problem. We can remove it by solving Eqn. 1 for t and plugging into Eqn. 2: t = .940d vo cos 00 .940d vo cos o -) - 12/19 ( Cleaning up and plugging in g = 9.8m: .342d = (v₁ sino) ( .940d vo cos 00 2
