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

Question

Quizplus · Accepted Answer

The speed of the block can be found using energy conservation. The potential energy at the top is converted to kinetic energy at the bottom. Using the formula v = sqrt(2gh), where h = 30.0 * sin(17°), the speed v is approximately 13.1 m/s.
