    Cannon Projectile
AI Thread Summary
The discussion focuses on calculating the maximum height and range of a projectile launched at various angles, specifically 60, 45, and 30 degrees, with an initial speed of 30.0 m/s. Participants emphasize that high school physics problems typically ignore air resistance and mass, simplifying the calculations. There is a debate about the complexity of the topic, with some asserting that it should be manageable for students if they understand kinematic equations. The conversation highlights the importance of grasping the foundational concepts in physics to solve these problems effectively. Overall, the thread underscores the need for clarity in understanding projectile motion without external factors.

A cannon shoots a projectile at an angle of 60 degrees above the horizontal with an initial speed of 30.0 m/s.

A) calculate the maximum height of the projectile and its range ( the horizontal distance traveled when the projectile hits the ground).

B) repeat the calculations of part A for initial angles of 45 degrees and 30 degrees, assuming the same initial speed of 30.0 m/s.

you havnt said your ideas about the question... whether you need to take into account air resistance or the mass of the object... so essentially it could be a mass less projectile in a vacuum crusing along until the end of the universe? lol...

That's all the information I have. This seems to complex for high school physics. I thought we were supposed to just learn the basics...
 
Heh, this isn't complex at all. In high school, especially since your physics class just started, you won't have air resistance. You should be able to do this easily if you read the material or listen to the teacher in class. Do you have all of your kinematic equations memorized?

I do listen. I just don't get it. That's why I'm here asking for help. No, it's an open notes test
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
