A bird moves with velocity 20m/s in a direction making an angle of 60 degree with the eastern line and 60 degree with vertical upwards. The velocity vector in rectangular form :

 

a) 10 i + 10 j + 10 k

 

b) 10 i +10(2)^1/2  j + 10 k

 

c) -20 i +10(2)^1/2  j + 20 k

 

d) 10(2)^1/2 i + 10 j + k

 

Dear balbir.kumar200@gmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

A vector cannot make an angle of 60 degree with the eastern line and 60 degree with vertical upwards simultaneously. We would request you to clarify/check the details provided so that we may answer this to the best of the ability.
