Homework Help Overview

The discussion revolves around problems related to momentum and force in the context of physics, specifically involving a golf ball and joggers. The original poster presents a scenario involving a golf ball's velocity, mass, and the duration of impact with a club, seeking assistance in calculating the change in momentum and the average force applied. Another participant introduces a separate problem involving two joggers and their momenta.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants question the necessary equations for calculating momentum and force, with one seeking guidance on how to initiate the problem. Another participant suggests finding the components of momentum for the joggers as a way to approach the second problem.

Discussion Status

The discussion is ongoing, with participants offering hints and suggestions without reaching a consensus. There is an acknowledgment of the challenges faced by the original poster and a willingness to assist in clarifying the problems presented.

Contextual Notes

Participants are navigating through two distinct problems, each with its own complexities. The original poster expresses uncertainty about the starting point for the golf ball problem, while the second problem involves vector components and directionality in momentum calculations.

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...
