Aperson standing on a cliff extends their arm past the cliff's edge and throws a stone with velocity 16.0 m/s downward. the stone is 80.0 m above ground when it leaves the person's hand. a) draw a diagram of the problem and label the known and unknown quantities. b) when will the stone land? c) what is the stone's velocity when it lands? show your work

b) 6.03 seconds

c) 43.164 m/s

Explanation:

t = Time taken

u = Initial velocity = 16 m/s

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

So, the stone would travel 13.05 m up

So, total height of the stone would fall is 13.05+80 = 93.05 m

b) The stone will land 1.63+4.4 = 6.03 seconds later

c) The stone's velocity when it lands is 43.164 m/s

Ifound this on google “the middle ear contains three tiny bones known as the ossicles: malleus, incus, and stapes. the ossicles were given their latin names for their distinctive shapes; they are also referred to as the hammer, anvil, and stirrup, respectively.” i hope this you for what your looking for
