Teaching myself physics of Perpeltion angle

AI Thread Summary
The discussion focuses on understanding the physics of throwing a ball, specifically the equations needed to analyze various factors like starting height, distance, and applied force. Key elements include initial velocity, angles, gravity, and mass, which all influence the ball's trajectory. It is noted that air resistance is not considered in the calculations. The relationship between force, mass, and acceleration is highlighted, with the formula F = m*a being essential for determining initial velocity. Overall, the conversation aims to provide foundational equations and concepts for analyzing projectile motion.

Homework Statement


Im try to teach myself the physics behind throwing a ball. Its for an independent study I am doing for a grade 11-2 math corse. I am having trouble with coming up with equations to help me figure out different parts of the over all picture of throw a ball.

I.E The starting hight, the d/t, and the force applied when given other varibables.



Homework Equations


Air resictence is not applied.


The Attempt at a Solution


I know that the equation involves angles, hight, inital velocity, gravity, mass, time, and distance...?

Welcome to PF.

Trajectories depend on the initial velocities and direction and gravity. After release it's just gravity until the Earth intervenes.

The initial velocity will depend on mass and force to accelerate the mass to its initial velocity.

Here are some formulas that will help you with the kinematics of motion.

Those and F = m*a should give you a good start.
 

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'

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...
