Ответ:
In this answer, the value of the acceleration of gravity is taken as 9.8 m/s2
Coefficient of static friction = 0.409
Explanation:
Kinetic friction is responsible for bringing the crate to rest.
Initial velocity, u = 4 m/s
Final velocity, v = 0 m/s
Distance, s = 2.5 m
We use the equation of motion to find the acceleration, a.
The negative sign denotes the crate was decelerating.
Kinetic friction = mass of crate × acceleration
Coefficient of kinetic friction = kinetic friction/weight of crate
is 80% of , coefficient of static friction
