In your FBD include A, B, P and link AOB. With this choice, you can simplify your angular impulse-momentum analysis since you do not need to deal with the impact force between P and A since it will be ...

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 ...

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 ...
