Alright, I am working a similar problem, but I don't understand what you said in the last section. I understand this part:
but after that, I simply get lost. How is the percentage for the blood pressure difference ACTUALLY calcuated from here? Sorry for unearthing this post, but any help...
Ah, it's always the positives and negatives. Thanks.
for part b, I am just going to use the same equation, with the delta x as the variable to be found, setting the final velocity to 0?
so, setting that up, it would be
v^{2}=v^{2}_{0}+2a\Deltax
0= (350 m/s)^{2} - 2(1.0 x 10^{6})...
Homework Statement
36 g bullet, speed of 350 m/s strikes a 8 cm fence post. It is retarded by an average Force is 3.6 x 10^{6} N while going through the post.
a. Speed of bullet when it emerges?
b. How many boards could the bullet penetrate?
