The free-fall acceleration at the surface of planet 1 is 22 m/s^2. The radius and the mass of planet 2 are twice those of planet
1 answer:
Answer:
g₂ = 11 m/s²
Explanation:
The value of free-fall acceleration on the surface of a planet is given by the following formula:
where,
g = free-fall acceleration
G = Universal Gravitational Constant
m = mass of the planet
r = radius of planet
FOR PLANET 1:
--------------------- equation (1)
FOR PLANET 2:
using equation (1):
<u>g₂ = 11 m/s²</u>

Answer:
Explanation:
We will apply the equations of kinematics to both stones separately.
First stone:
Let us denote the time spent after the second stone is thrown as 'T'.
Second stone:
Answer: Just before its hits the ground it becomes kinetic energy and when it hits the ground it becomes in another form of energy (acoustic energy or thermal energy, for example)
Explanation:
Energy is the ability of matter to produce work in the form of movement, light, heat, among others.
In this sense, according to the Conservation of Energy principle: <em>"energy is not created or destroyed, it is transformed."</em>
So, in the case of the apple, its total energy is conserved.
When the apple is hanging from a limb, it has zero kinetic energy (because it is at rest) and has gravitational potential energy
, which depends on the mass
, the acceleration due gravity
and the height
:
When the apple falls, just before its hits the ground, this gravitational potential energy transforms in kinetic energy (since the apple is moving), which depends on the mass and velocity
of the apple:
When the apple hits the ground, the gravitational potential energy is zero (h=0) and the kinetic energy transforms into some other form of energy (acoustic energy or thermal energy, for example).
