1A. You're feeding the fish at the pond by the baseball field and decide to do some physics calculations. You notice that you release the fish food 1.65 m above the surface of the water, and during one throw, when the food left your hand at 3.20 m/s with a direction of 13.0° below the horizon, you managed to hit a fish near the surface. How fast was the food going right before it hits the fish? 1B.Two kittens are running toward each other, one is named Chloe and the other is named Luna. Luna runs at a speed of 1.40 m/s.
