A 5kg block slides down a frictionless incline from 6m height. What is its speed at the bottom? (Take g\=10m/s2)

Options

Choose one · Correct answer highlighted

Explanation

Potential energy mgh=5×10×6=300J. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 11 m/s. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
