Bonnie and Clyde are sliding a 325 kg bank safe across the floor to their getaway car. The safe slides with a constant speed if Clyde pushes from behind with 377 N of force while Bonnie pulls forward on a rope with 353 N of force. Required:
What is the safe's coefficient of kinetic friction on the bank floor?

the safe's coefficient of kinetic friction on the bank floor is

Explanation:

GIven that:

Bonnie and Clyde are sliding a 325 kg bank safe across the floor to their getaway car.

So ,let assume they are sliding the  bank safe on an horizontal direction

Clyde  →  Δ(bank safe)  → Bonnie

Also; from the above representation; let not forget that the friction force is acting in the opposite direction ←

where;

 =

The safe slides with a constant speed

If Clyde pushes from behind with 377 N of force while Bonnie pulls forward on a rope with 353 N of force.

Thus; since the safe slides with a constant speed if the two conditions are met; then the net force acting on the slide will be equal to zero.

SO;

Since the net force acting on the slide will be equal to zero.

Then;

Also; let and

Then;

where;

Then;

Thus; the safe's coefficient of kinetic friction on the bank floor is
