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's mass was 0.19 g, its speed before entering the branch was 195 m/s, and its penetration depth was 16 mm. If its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick
