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

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
