Question

1. Two particles A and B start moving with velocities
20 m/s and 30/2 m/s along x-axis and at an angle
45° with X-axis respectively in xy-plane from origin.
The relative velocity of B wrt. to A​

Answer 1

it's option (1)
it's better to solve by your own
let me give you some hints

just hints:
1. draw xy-plane
2. vel. of particle B is 30√2•sin45°
3.apply relative velocity formula

**(you will get the answer as option 1)

thank me later!
