To solve this problem we will apply the concepts related to the equations of linear motion and angular motion in order to find the radius. Our values are given as,

Then

The relation between the acceleration and the angular velocity and the radius is,

The angular velocity and the lineal velocity can be related as,

The acceleration and the velocity was given, then


Replacing at the first equation we have,



Now using this expression to find the radius we have that



Therefore the correct answer is C.
Answer:
Condition

Explanation:
Basically black hole is an object from which light rays can not escape it means to go out from gravitational field , that body should thrown with speed greater then light.
Let's do some calculation
Gravitational potential at surface =
If we give kinetic energy equal to magnitude of Potential energy as on surface it will escape.
=
⇒
It will be more better for black hole if above ratio (analogous to density ) is more then above calculated
The example of Newton's second law is that a runner accelerates at a rate of 1 meter per second per second during the race. The correct answer is C.
To solve the problem you must first know that by keeping the linear moment P1 = P2. You must find P1 from the system and equal it to P2 of the system, from that equation you clear the final velocity 1. Which will result in V1f = 60.16 cm / s to the north.I attach the solution.
Option C is the right answer
