A ball rolls off the table with a velocity of 1.8 m/s. The table is 2.2 m high

Answer 1

Perhaps you meant to ask how long it takes to hit the ground and how far it travels horizontally.

Time t to hit ground:

h = gt²/2 ⇒

t = √(2h/g)

Plug in

h = 2.2 m

g = 9.8 m/s²

and get t in seconds.

Horizontal distance:

x = vt

Plug in

v = 1.8 m/s

t = ? (result from above)

and get x in meters.
