Answer:
1. 218.55 N
2.
3.
Explanation:
Part 1;
Net force where m is mass, g is gravitational force and is the angle of inclination
Frictional force, is given by
where is the coefficient of static friction
Since , therefore, the block doesn’t slip and the frictional force acting is mgh=218.55N
Part 2.
Using the relationship that
Frictional force
The maximum angle of inclination
Part 3:
Net force on the object is given by
where is the coefficient of kinetic friction
= 9.8 ( sin 38 - (0.51) cos 38 )
=
