Answer:
2966.257 m
Explanation:
c = Speed of light = 3×10⁸ m/s
M = Mass of black hole = 2×10³⁰ kg
G = Gravitational constant = 6.67408 × 10⁻¹¹ m³/ kg s²
Schwarzschild radius
∴Schwarzschild radius of the black hole is 2966.257 m
If the man DECREASES the force of his push on the cart, the cart slows down.
<h3>
Force acting on body</h3>
The force applied to an object is determined by applying Newton's second law of motion.
F = ma
where;
- m is mass of the body
- a is acceleration of the body
a = Δv/t
F = (mΔv)/t
mΔv = Ft
Δv = Ft/m
From the equation above, when the applied force decreases, the change in velocity decreases.
Thus, if the man DECREASES the force of his push on the cart, the cart slows down.

I believe the correct gravity on the moon is 1/6 of Earth.
Take note there is a difference between 1 6 and 1/6.
HOWEVER, we should realize that the trick here is that the
question asks about the MASS of the astronaut and not his weight. Mass is an
inherent property of an object, it is unaffected by external factors such as
gravity. What will change as the astronaut moves from Earth to the moon is his
weight, which has the formula: weight = mass times gravity.
<span>Therefore if he has a mass of 50 kg on Earth, then he will
also have a mass of 50 kg on moon.</span>
