Answer:
[tex]v_x=34 m/s[/tex]
[tex]v_y=53.9\ m/s[/tex]
Explanation:
Horizontal Launch
When an object is thrown horizontally with a speed v from a height h, it describes a curved path ruled by gravity until it eventually hits the ground.
The horizontal component of the velocity is always constant because no acceleration acts in that direction, thus:
vx=v
The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:
[tex]v_y=g.t[/tex]
The horizontal component of the velocity is always the same:
[tex]v_x=34 m/s[/tex]
The vertical component at t=5.5 s is:
[tex]v_y=9.8*5.5=53.9[/tex]
[tex]v_y=53.9\ m/s[/tex]
