24. The velocity of a boat relative to water is represented by 3i+4j and that
water relative to the earth by i - 3j. What is the velocity of the boat relative to the
earth, if i and j represent velocities of 1 km/hour east and north respectively

Answer:

Velocity of boat with respect to ground is Vbg = (3i + 4j) and the velocity of river water moving with respect to Vrg=(-3i - 4j). Thus, to find the velocity of the boat with respect to the water will be Vbr.

Answered by Monisha748

Step-by-step explanation:

Vbr = (3i + 4j) - (-3i - 4j). Vbr = 6i + 8j. So, the velocity of the boat with respect to the water will be in the form 6i + 8j. The velocity will be V = = 10
