Answer:All balls have same velocity
Explanation:
Ball A
horizontal velocity
vertical velocity
let h be the height of building
Vertical velocity acquired by Ball A
Velocity just before hitting ground=
Ball B
launched with velocity u at angle of 45 above horizontal
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Ball C
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Thus all three balls will have same final velocity.
Answer:
1 4.5 divede by 1.29 I think that is the literal answer
On a clear cloudless day, the sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light.

Hope this helps! :)
