A 1.8 kg block slides down a ramp, as shown in the figure. (Figure 1) The ramp in the figure is not frictionless. The top of the ramp is h1 = 1.5 m above the ground; the bottom of the ramp is h2 = 0.40 m above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance d away. Friction on the ramp does -9.7 J of work on the block before it becomes airborne.
