Question 5 A leave falls from a height of 5 meters above the ground. It lands with a speed of 1 m/s. How much work did the ai

Answer 1

Answer #1

Concept - Here we use work energy theorem where work done by air plus work done by gravity is equal to change in kinetic energy of the leaves.

Wair + Wgravity = OKE on Wair + mgh = & mu? -o, So, Wair = -0.2425/5 Wair mao v: 1w)s m=000 Sig
