- Homework Statement
- There are 3 particles a, b and c. A moves towards B with velocity 5 m/s and B moves towards A with same speed as A. C moves such that separation between B and C is always 40 and separation between A and C is always 30. initial distance between A and B was 50m. Find velocity of C as a function of time.
- Relevant Equations
- dr/dt = v
I tried to solve using trigonometry.
Let angle between line CA ad BA be theta and angle between BA and AC be alpha.
30sin theta= 40 sin alpha
30 cos theta + 40 cos alpha + 2vt=50
I have no idea how to proceed after this.
