What are the components of the pinecone's impact velocity parallel and perpendicular to the ground?Explanation / Answer
Pinecone falls down straight from pine tree angle 20 and pinecone hits group with speed 10m/s.
Here, angle is 20 and velocity 10 m/s.
a) when component parallel to ground is
= 10m/s × sin20
= 10 × 0.342
= 3.42m/s.
b) when component perpendicular to the ground is
= 10m/s × cos20
= 10m/s × 0.939
= 9.39m/s.
