Spiral galaxies are most common
Answer:
Explanation:
Given
mass of laptop m=2 kg
The velocity of car u=8 m/s
The coefficient of static friction is
The coefficient of kinetic friction is
As the car is moving, so the coefficient of kinetic friction comes into play
deceleration offered by friction
Using the equation of motion
insert the values
If you were given distance & period of time, you would be able to calculate the speed.
Hope this helps!
