AI Thread Summary
To calculate the least and greatest elevation angles for a football kicker to score a field goal from 48 meters away with an initial speed of 30 m/s, one must apply the principles of projectile motion. The horizontal distance and the height of the goalposts (3.44 m) are key factors in determining the angles. The equations of motion for both the x and y directions need to be used to solve for the angles. The discussion emphasizes the importance of breaking down the problem into components and using standard constant acceleration equations. Understanding these concepts is crucial for accurately determining the required angles for the kick.

Homework Statement



A football kicker can give the ball an initial speed of 30 m/s. What are the (a) least and (b) greatest elevation angles at which he can kick the ball to score a field goal from a point 48 m in front of goalposts whose horizontal bar is 3.44 m above the ground?

hi sagaradeath! :wink:

show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 
thatz the thing i don't know how to start it
 
call the angle θ, and use standard constant acceleration equations for the x and y directions (separately)
 

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...
