To find the force of static friction, we need to first calculate the net force acting on the bin.
The force of the child pulling to the right is 20 N, and the force of the father pulling to the left is 50 N.
Therefore, the net force = 50 N - 20 N = 30 N to the left.
Since the bin doesn't move, the force of static friction must be equal in magnitude but opposite in direction to the net force.
Therefore, the force of static friction = 30 N to the right.
So, the force of static friction is 30 N.
Two people pull on a large bin with a mass of 70 kg. The child pulls to the right and the father pulls to the left.
Find the force of static friction if the child pulls with 20 N [right] and the father pulls with 50 N [left], and the bin doesn’t move.
