An object is projected horizontally with the velocity 4ms from a height of 20 m the horizontal displacement is angle x class=

Respuesta :

Answer:

Δx = 8 m

Explanation:

The time needed to fall from vertical rest

h = ½gt²

t = √(2h/g)

t = √(2(20)/9.8)

t = 2.0 s

the horizontal distance traveled in that time is

d = vt

d = 4(2)

d = 8 m
