Answer:
Coefficient of static friction will be equal to 0.642
Explanation:
We have given acceleration
Acceleration due to gravity
We have to find the coefficient of static friction between truck and a cabinet will
We know that acceleration is equal to , here
is coefficient of static friction and g is acceleration due to gravity
So
So coefficient of static friction will be equal to 0.642
