Question

If Va= 300 km/hr and Vb= 350 km/hr. Va is in opposite direction of Vb. We know that relative velocity of A with respect to B is Vab= Va-Vb. Then why the answer is Vab= 300-(-350) = 650 and not 300-350= 50 ??????pls explain it is urgent ​

Answer 1

Answer:

350-(-300)=650

Explanation:

since both are in opposite directions i.e., one of the velocity is negative to other. '-' sign should be considered for velocity which is opp. in direction
