Answer:
Hey
(note you have forgotten your diagram so this may not be what you where hoping for.)
The important discovery that galilao made was that he proved that <em><u>all objects no matter their mass fall at the same rate.</u></em>
That is to say that a bowling ball falls at the same rate as a truck.
Answer:
U₁ = 129.4 J
Explanation:
The potential energy is
U = mg y - m g y₀
Where I correspond to the initial position, with this it is an additive constant, we can make it zero with the placement of the reference system, in this case the system is placed on the floor where the ladder rests.
The power power for people on the floor is
U₀ = 0 J
The potential energy for the person on the first step is
U₁ = m g y₁
In general the steps are 20 cm high
y₁ = 20 cm (1m / 100cm) = 0.20 m
U₁ = 66 9.8 0.20
U₁ = 129.4 J
