Energy Conservation with Conservative Forces: a Block Slides Down a Frictionless

Energy conservation with conservative forces: A block slides down a frictionless inclined ramp. If the ramp angle is 17.0° and its length is find the speed of the block as it reaches the bottom of the ramp, assuming it started sliding from rest at the top.

A) 13.1 m/s
B) 172 m/s
C) 9.26 m/s
D) 24.0 m/s
