Calculating Projectile Trajectory Without Air Resistance

AI Thread Summary
To calculate the trajectory of a projectile without air resistance, the key formula is the range equation: R = (v^2 * sin(2θ)) / g, where R is the range, v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity (approximately 32.2 ft/s²). For a cannon fired at 1440 ft/s on level ground at a 45-degree angle, the round will land at a distance of 1440^2 / 32.2 feet. The discussion emphasizes the importance of understanding the launch angle and initial velocity for accurate calculations. Resources like HyperPhysics are recommended for further exploration of projectile motion concepts. This approach provides a straightforward method to determine where the projectile will land.

Greetings,

Before I begin my problem, I would like to confess that I understand almost nothing about physics. My math is limited to what I am doing in class right now as a ninth grader ( I understand quadratics...). I am doing a research project, and I need some help.

Homework Statement



What I am looking for is the trajectory formula when firing a cannon with no air resistance. For example, If I fired a cannon on level ground, and fire a round at 1440 ft/s, where will my round land if it does not encounter any obstacles.


Homework Equations



Please show me a formula I can use for this, and where i plug in the numbers.

Thanks in advance.

Thread 'Errors and significant figures'

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'

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...
