Practice Problem

A 2 kg block slides down a frictionless ramp angled at 30°. What is the acceleration of the block along the ramp?

Use: g = 9.8 m/s²

Step-by-step Guide
1
Draw a free-body diagram. Identify forces: gravity mg downward and normal force perpendicular to surface.
2
Resolve gravity along the ramp. Component parallel to surface = mg·sin(30°)
3
Apply Newton's 2nd Law. a = g·sin(30°) = 9.8 × 0.5 = 4.9 m/s²
