  1. Since the cable is broken, if the coordinates are set to be even with the crate, would the sum of forces in the x =0? Or would the friction not allow that?

    1. You are correct in thinking that friction creates a force on the crate along the direction of the incline. Therefore, momentum is not conserved in the x-direction. However, you can still use the linear impulse/momentum equation to relate the change in velocity to the change in time.
