Ablock slides down a frictionless inclined ramp. if the ramp angle is 17.0° and its length is 30.0 m, find the speed of the block as it reaches the bottom of the ramp, assuming it started sliding from rest at the top.

 v = 17.15 m/s

Explanation:

given,

angle of ramp = 17.0°

length of ramp(l) = 30 m

height of the ramp =  

            h = 15 m

using energy of conservation

 v = 17.15 m/s

 speed of block reaching at the bottom = v = 17.15 m/s
