What constant force does the punter exert on the ball?

AI Thread Summary
To determine the constant force exerted by a punter on a football, the problem involves a 0.55 kg ball accelerated to 8.0 m/s in 0.25 seconds. The calculated force of 19.7 N was questioned, with a recalculation suggesting the correct force is 17.6 N. The acceleration was derived as 32 m/s², leading to the formula f = ma, where f is force, m is mass, and a is acceleration. The discussion highlights the importance of accurate calculations in physics problems.

Could someone help me with this problem?

A football punter accelerates a 0.55kg football from rest to a speed of 8.0 m/s in 0.25s. What constant force does the punter exert on the ball?

The force I got was 19.7 N. Is this right?

How did you get that answer?
 
17.6 no?

f = ma

f = ?
m = 0.55
a = 32 -> 4*8=32

f = 0.55*32
f = 17.6N
 

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...
