Answer:
Explanation:
Given that,
A lady falling has a final velocity of 4m/s
v = 4m/s
Mass of the lady is 60kg.
m = 60kg
Using conservation of energy, the potential energy of the body from the point where the lady is dropping is converted to the final kinetic energy of the lady.
Therefore,
P.E = K.E(final) = ½mv²
P.E = ½ × 60 × 4²
P.E = 480 J.

Answer:
The value is
Explanation:
From the question we are told that
The mass of the first lead sphere is
The mass of the second lead sphere is
The separation between masses is
Generally the gravitational force between each sphere is mathematically represented as
Here G is the gravitational constant with value
