The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. in a laboratory simulation, a standard wood toothpick was shot by pneumatic gun into an oak branch. the toothpick mass was 0.12 g, its speed before entering the branch was 224 m/s, and its penetration depth was 15 mm. if its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick?
