At a distribution depot, a parcel is released from rest at point HHH at the top of a curved gravity chute. The parcel slides down the chute to point LLL at the bottom, where it transitions onto a horizontal conveyor belt.

An engineer wants to repeat the dispatch from point HHH but requires the parcel to arrive at point LLL with a greater speed.
Suggest two physical changes to the system or the initial release conditions that would achieve this.
