Motion Projectile Projectile motion Trajectory

AI Thread Summary

To determine the minimum velocity and angle for a ball to clear a 100 m wall located 100 m away, one must apply the principles of projectile motion. The ball must be launched at an optimal angle, typically 45 degrees, to maximize horizontal distance while achieving the necessary vertical height. The vertical velocity needed to reach the wall's height can be calculated using the equation for vertical motion, factoring in gravity. The horizontal component of the velocity must also be sufficient to cover the 200 m distance to point B. A step-by-step calculation involving these components will yield the required launch velocity and angle.

Homework Statement

There is a point A and point B, with 200 m distance between the two. In the center, there is a 100 m wall. What is the minimum velocity (and angle) a ball must be thrown to get over the wall?

Basically I'm clueless. I need step by step instructions.

THANKS!

What is the vertical velocity required to cross that wall?

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
