Two equal masses (m) are projected at the same angle (θ) from two points separated by their range with equal velocities (v). The momentum at the point of their collision is
A
Zero
B
2 mvcosθ
C
– 2 mvcosθ
D
None
Answer
Zero
Explanation
Solution
Both masses will collide at the highest point of their trajectory with equal and opposite momentum. So net momentum of the system will be zero.
