[QUOTE="duchuy, post: 6456234, member: 686238"] [B]Homework Statement:[/B] How deep in a tree would a mass m firearm projectile penetrate at velocity v0 if the frictional force between the projectile and the wood is C ? [B]Relevant Equations:[/B] d = mv^2 / 2C Hi, I was given this exercice where I have to calculate the penetration distance, knowing that m = 20g, v = 300km/h and C = 750 N and I have to give the results with two significant numbers. I really thought that all I had to do was replace the values so I did : d = (20.10^-3) x (300/3,6)^2 / 2x750 and I ended up with d = 0,0925925925... But when I entered the answer with two significant figures = 0,093, the answer was wrong. Please help me find me find my mistake thank you so much! Sorry if i have misused any term, I translated this from french. [/QUOTE]
