Answer:
a) F1=17N, F2=32N
b) F1=26N, F2=54N
Step-by-step explanation:
Now for starters we have to get some things
right:
.Friction acts in a direction as to opposes the applied force
.Before motion takes place the frictional force is equal to the applied force.
.A body is said to be in equilibrium when all the forces acting on it sum up to zero
.A body moving at a constant velocity is said to be in a dynamic equilibrium.
a).For this situation the statue is at rest and has not moved(no motion has taken place) now F1 in the problem is clearly the frictional force,by observation, And F2 the normal reaction.
hence since the statue is at rest then F1 is 17N and F2=32N
now since they are in a equilibrium (-17+17+32+(-32))=0
b). since it's pulled, it at constant velocity it is also in an equilibrium and F1+60=86,F1=26N
and F2=54N
The body moving at a constant velocity is at equilibrium since it has not accelerated, just like you sitting you are also in equilibrium since you haven't accelerated.
