Taking projection point aa origin
Horizontal direction
Position after 3 s =20x3=60m
Velocity remains 20 m/s
Vertical direction
V=u+at
=3x 10=30 m/s
Position
Distance covered in downward s=5x9=45m
Therefore position is (60,-45)
V is 20i  - 30j
Hope thiy helps u
Please approve if it helped u   :)
All the best
