The escape velocity from the planet is 5052 m/s
Explanation:
The formula to calculate the escape velocity from a planet is:
where
is the gravitational constant
M is the mass of the planet
R is the radius of the planet
For Earth,
is the mass
is the radius
Here we have a planet that:
- its mass is 10.8% of that of Earth, so
- its radius is 53% of that of Earth, so
Substituting everything into the first equation, we find the escape velocity from this planet:

Answer:
Their translational kinetic energies are the same
Explanation:
The translational kinetic energy of an object is given by the formula:
Where m = the mass of the object and
v = the linear speed of the object
From the question, it is stated that wheel A has the same mass as wheel B, that is
Linear speed is also a function of the distance covered. Since both wheels cover the same distance within the same interval, we can conclude that
Both wheels A and B have equal speed and mass, this means that their translational kinetic energy is the same.
Note that translational kinetic energy is not a function of the radius
