That is a vector. It is a combination of direction and velocity. (You can think of Vector from Despicable Me to help you remember the term)

It is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game.
<h3>
What is a motor crash?</h3>
A motor crash is the event in which a motor vehicle is involved in a collision amongst another motor vehicle, pedestrian, animal, or stationary object.
<h3>Impact of motor crash</h3>
A motor crash can cause the following;
- total damage of the car
- breaking of bones of the driver
- damage of properties colliding with the car
Thus, it is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game. In the video game he will not be involved physically with the motor crash.

Answer:
The required angular speed the neutron star is 10992.32 rad/s
Explanation:
Given the data in the question;
mass of the sun M = 1.99 × 10³⁰ kg
Mass of the neutron star
M = 2( M )
M = 2( 1.99 × 10³⁰ kg )
M = ( 3.98 × 10³⁰ kg )
Radius of neutron star R = 13.0 km = 13 × 10³ m
Now, let mass of a small object on the neutron star be m
angular speed be ω.
During rotational motion, the gravitational force on the object supplies the necessary centripetal force.
GmM = / R² = mRω²
ω² = GM = / R³
ω = √(GM = / R³)
we know that gravitational G = 6.67 × 10⁻¹¹ Nm²/kg²
we substitute
ω = √( ( 6.67 × 10⁻¹¹ )( 3.98 × 10³⁰ ) ) / (13 × 10³ )³)
ω = √( 2.65466 × 10²⁰ / 2.197 × 10¹²
ω = √ 120831133.3636777
ω = 10992.32 rad/s
Therefore, The required angular speed the neutron star is 10992.32 rad/s
A centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path
