Question

to the driver of the car A moving with velocity V = (3i+4j) m/s , a second car B appears to have a velocity (5i+12j) m/s. the true velocity of a car B is​

Answer 1

Explanation:

As first we should know the value of I and j. The value if I and j is √-1. so on subsisting the values we get the velocity of car A and B. As per your question the velocity of Car B is 17√-1 m/s. Hope it helps you. Thank you.
