# Potential energy and conservative forces: block slides down a frictionless ramp

1. A 1.9-kg block slides down a frictionless ramp. The top of the ramp is 1.5 m above the ground; the bottom of the ramp is 0.25 m above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance d away. Find the distance d.

2. Suppose the ramp is not frictionless. Find the distance d for the case in which friction on the ramp does -9.7J of work on the block before it becomes airborne.
