Question

A block of mass 5 kg is placed on a frictionless incline of angle $30^\circ$. What is the acceleration of the block down the incline? (Take $g = 9.8\, m/s^2$)

• A. \(9.8\, m/s^2\)
• B. \(4.9\, m/s^2\)
• C. \(5.6\, m/s^2\)
• D. \(3.2\, m/s^2\)

Hint:

On an incline, acceleration of an object without friction is \( a = g \sin \theta \).
