I have broken down the forces and I am not sure if I am right. I will re-edit my working again. (Note: Force P is parallel to the horizontal ground.) F(gx) = Force parallel to the inclined due to gravity. F(gy) = Force perpedicular to the inclined due to gravity. F(px) = Force parallel to...

Sorry let me re edit again for F(xNet) Let F(f) = Frictional Force F(xNet) = Total horizontal net force = F(x) + F(px) - F(f) = mg(sin(theta)) + P(cos(theta)) - F(f) = 1000sin20 + Pcos20 - F(f) I still can't figure how to find the frictional force. I know F(f) = F(N) * mu = F(yNet) *...

Homework Statement A block with a mass of 100kg is being pulled with a force P in and effort to move it down the ramp. The ramp makes a 20 degree with the horizontal ground. The coefficient of the friction between the ramp and the block is 0.7. Find the frictional force and the horizontal...

Oh so sorry! Yes I got. magnitude of Horizontal velocity= 30m/s. Horizontal distance = 90m Sorry made a very bad typo. Thank you for the confirmation PWiz

Ohhh! I keep thinking because it is an arc and didn't break down into it's horizontal and vertical direction. Here is what I did. Please correct me if I am wrong. I understand that horizontal distance is constant = 30m/s So I know the time taken is 3.0sec. 30x3 = 90m. Therefore, horizontal...

Hi PWiz. No I have not learned projectile motion. How should I understand the concept? Thanks

Homework Statement Consider a cannonball being fired with a velocity of 30m/s from a cliff of height 45m. http://imgur.com/OCMNEPv (a) Calculate the time taken for the ball to reach the ground. (b) Calculate the range of the motion. (c) Calculate the horizontal velocity, vertical velocity...

Thank you. I really apologise for my mistake. I didn't do a search on that two uni. I do know that two uni, I just assumed they did not offer it. Thank you. I already know what to do.

thank you for your response! But where can I find a degree that offers Physics Major? The reason is because, there is no Physics Major in my country. Of course I don't mind starting from the beginning, I actually expected to put myself to start from the beginning. But the problem is, I kept...

Hi all. Need Advice. Thank you :) Hi all. Sorry if this kind of question has been posted but I try googling my question, so here is where I end up. Most of the threads that I read didn't actually specifically answer my question. Anyway, my question is, "How do I study and become a...
