A block slides down a frictionless inclined ramp.If the ramp angle is 17.0° and the length of it is 30.0 m,find the speed of the block as it reaches the end 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

The speed can be found using energy conservation: potential energy at the top equals kinetic energy at the bottom. The height (h) is 30.0 m * sin(17.0°). Using the formula v = sqrt(2gh), where g = 9.8 m/s², the speed is approximately 13.1 m/s.
