C. Insulator
It COULD be semi-insulator but i'm sure its C
Car is moving on the glassy slope with constant speed
Now we know that
![a = \frac{dv}{dt}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7Bdv%7D%7Bdt%7D)
so acceleration is rate of change in velocity
as we know that velocity is constant here so acceleration is zero
so here
![a = 0](https://tex.z-dn.net/?f=a%20%3D%200)
now as we know by Newton's II law
![F = ma](https://tex.z-dn.net/?f=F%20%3D%20ma)
since a = 0
![F = 0](https://tex.z-dn.net/?f=F%20%3D%200)
so net force will be ZERO on it during this motion
<u>Answer:
</u>
Cat has 2.02 seconds to right itself.
<u>Explanation:
</u>
Initial height of cat from ground = 20 meter.
We have equation of motion ,
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this the velocity of cat in vertical direction = 0 m/s, acceleration = acceleration due to gravity = 9.8
, we need to calculate time when s = 20 meter.
Substituting
So, cat has 2.02 seconds to right itself.
