AI Thread Summary
The discussion centers on solving a physics problem involving a golf ball's momentum and force after being struck by a club. The golfer imparts a velocity of +33 m/s to a 0.045 kg ball over a contact time of 4.45 ms. Participants are seeking guidance on calculating the change in momentum and the average force exerted on the ball. Additionally, a related problem involving two joggers' momenta is mentioned, with advice given to find the components of each jogger's momentum for summation. The thread emphasizes the need for clarity in applying impulse and momentum equations to solve these problems.

Homework Statement



A golfer, driving a golf ball off the tee, gives the ball a velocity of +33 m/s. The mass of the ball is 0.045 kg, and the duration of the impact with the golf club is 4.45 10-3 s.

(a) What is the change in momentum of the ball?
kgm/s

(b) Determine the average force applied to the ball by the club.
N


Homework Equations



what equation are needed?

thank you, this is the second problem I am stuck on...any help is appreciated.

An 85 kg jogger is heading due east at a speed of 2.2 m/s. A 55 kg jogger is heading 34° north of east at a speed of 2.8 m/s. Find the magnitude and direction of the sum of momenta of the two joggers.
 
Where are you stuck? Find the components of each jogger's momentum and add them up.
 
thanks for the help from both of you...
 

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...
