The weight of an object is given by
where m is the mass of the object, while g is the strength of the gravity (which corresponds to the gravitational acceleration of the planet).
In our problem, the shoes have a mass of m=0.5 kg, and their weight is F=11.55 N. So, we can re-arrange the previous formula to find the value of g:
and this is the strength of the gravity on Jupiter's surface.

Answer:
The velocity of the bus at B is
Explanation:
Let's take position B as base point .
From the diagram height between point B and A ia mathematically evaluated as
From the question we are told that
The velocity at location A is
According the law of conservation of energy
Where is the potential energy at A which is mathematically represented as
is the kinetic energy energy at A which is mathematically represented as
is the kinetic energy at A which is mathematically represented as
Where is the velocity at location B
So
Making the subject of the formula
Substituting values
