Don't get this 2d motion problem?

AI Thread Summary
The problem involves calculating the speed at which a second player must run to catch a football kicked at a 40-degree angle with an initial speed of 14.0 m/s, while standing 26.0 m away. The player must reach the ball just before it hits the ground, ignoring air resistance. To solve this, one must determine the time it takes for the ball to reach the ground and then use that time to calculate the required running speed. The key concept is understanding the projectile motion of the ball and the horizontal distance covered. The solution requires applying kinematic equations for both the ball's trajectory and the runner's motion.

don't get this 2d motion problem??

Homework Statement


a player kicks a football at an angle of 40.0 degrees above the horizontal with an initial speed of 14.0 m/s. Air resistance may be ignored. A second player standing at a distance of 26.0m from the first(in the direction of the kick) starts running to meet the ball at the instant it is kicked. How fast must he run in order to catch the ball just before it hits the ground?

i don't get the concept at how to do this when the question asks me "to catch the object before it hits the ground"
 


Just assume the player catches the ball a tiny tiny amount (effectively 0 meters) above the ground.
 
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...
