Answer:
The velocity of Q relative to P is 2.83 m/s.
Explanation:
Given that,
Velocity of P = 3 m/s
Velocity of Q= 5 m/s
We need to calculate the velocity of Q relative to P
Using cosine rule
Where, = velocity of Q
= velocity of P
Put the value into the formula
Hence, The velocity of Q relative to P is 2.83 m/s.
