A block is released from rest on a smooth inclined plane as shown. Find the magnitude of its acceleration along the incline in $\text{m/s}^2$. (Take $g = 10\ \text{m/s}^2$.)
Numerical value type. Enter your answer.
Answer: 5
Concept. On a smooth incline the only force along the slope is $mg\sin\theta$.
Step 1. Acceleration. $a = 10\sin30° = 5\ \text{m/s}^2$.
Answer. $5$.
