Suppose an object in freefall is dropped from a building it’s starting velocity is 0m/s. ignoring the facts of air resistance what is the speed (in m/s) of the object after falling three seconds?

v = v₀ + at

v = final speed, v₀ = initial speed, a = acceleration, t = elapsed time

Given values:

v₀ = 0m/s (starts from rest), a = 9.81m/s², t = 3s

Plug in and solve for v:

v = 0 + 9.81(3)

v = 29.4m/s

i'm just gonna leave this comment here, so i can get a challange done-

explanation:

explanation:

newton's third law, for every action there is an equal and opposite reaction.
