@ kuruman, i think at a high school/ introductory physics level we're allowed to assume that energy is conserved within the bullet-block system.
The solution is simple. It is a mere calculation using the conservation of energy.
0.5*m*v^2 = m*g*h
Theta is given to be 40 degrees. So in order...
@hikaru: Not quite yet, but i have 3 essays to rush out and some other tutorials to finish so I am going to leave looking for the non-calculus solution aside for now unless you would care to kindly enlighten me? =)
I've rechecked the solution N-Gin is actually right provided that it is ( as hikaru says ) VL not UL, but I'm still a little confused as to how he did the last step?
Hi thanks for the help so far everyone, i often browse through physics forums but only felt compelled to register after this question.
Kuruman could you help me to understand how you derived that equation? I follow the rest of your workings. And i think with the addition of equating the 2...
Yes i was about to ask as well. How did you solve (1) and (2)?
And hikaru would you kindly enlighten us as to the method/solution then? I'm trying to work it out but it has been hours. I'm really burnt over this question so a direct answer would be appreciated =)
P.S the answer is incorrect. I...
