Questions
As two boats approach the Mumbai, the velocity of boat I relative to boat 2 is 10 kmhr-1 in a direction of 60o north of east. If boat 2 has a velocity of l5 kmhr-1 due south. What is the velocity of boat 1 ?
detailed solution
Correct option is D
v→12=v→1−v→2⇒v→1=v→2+v→12Here, v→12=103cos60∘i^+sin60∘j^=53i^+15j^⇒ v→1=v→2+v→12=(−15j^)+(53i^+15j^)=53i^⇒ v→1=53km/hr due east.Talk to our academic expert!
