A+B together allows us to make the impact force internal (and not appear in the linear impulse-momentum equation). FBDs for A and B individually allows us to determine the t-direction components of ...

Also, consider the particle to be of small physical dimensions. What does your moment equation above say about the angular momentum of the system about point A?

Impulse-momentum can be used to calculate the average force on the ball. \(F = -72.5N \,\) (value is negative as moving to the left) The negative sign in front of the \(-72.5N\) indicates that the ...
