What is the landing velocity of an object that is thrown vertically down with a velocity of 5 m/s from a height of 25 m?

The relevant equation we can use in this case would be:

v^2 = v0^2 + 2 a d

where:

v is our final velocity or landing velocity = ?

v0 is the initial velocity = 5 m/s

a is acceleration due to gravity = 9.81 m/s^2

d is distance = 25 m

So:

v^2 = 5^2 + 2 (9.81) 25

v^2 = 515.5

v = 22.70 m/s

i think they are all correct

explanation:

they seem good

real, smaller and upside-down.   so the answer should be b.
