9. A fireworks shell is launched in a level field at an angle of 70 degrees with an initial speed of 100 m/s. b. Assume that at one point in its trajectory the projectile splits in two pieces, one with twice the mass of the other. If the larger piece lands 500 m from the launch point, where does the smaller piece land? [You don't have the mass but it does not matter. Call the mass of the small piece1.0 kg if you wish.] c. If, after the split, the horizontal velocity of the larger piece is 20 m/s, with respect to the ground, determine the horizontal velocity of smaller piece.
