An object is launched horizontally at a velocity of 19 m/s from the top of a building. It falls vertically a distance of 24m before it reaches the ground. How long does this projectile travel before reaching the ground?

2.2 s

Explanation:

His vertical initial velocity  u =0

vertical displacement h = 24 m .

vertical acceleration g = 9.8 m /s²

h = ut + 1/2 gt²

24 = 1/2 x 9.8 x t²

t = 2.2 s .

Time of fall = 2.2 s

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
