1. Pushing a Bor Two workers are sliding a 300 kg crate across the floor. One worker pushes forward on the crate with a force of 380 N while the other pulls in the same direction with a force of 350 N using a rope connected to the crate. Both forces are horizontal, and the crate slides with a constant speed. What is the crate's coefficient of kinetic friction on the floor?

Question
![1. Pushing a Bor
Two workers are sliding a 300 kg crate across the floor. One worker pushes forward on
the crate with a force of 380 N while the other pulls in the same direction with a force
of 350 N using a rope connected to the crate. Both forces are horizontal, and the crate
slides with a constant speed. What is the crate's coefficient of kinetic friction on the
floor?
2. Fun Friction Problem
A 4000 kg truck is parked on a 7.0 slope. Calculate the frictional force on the truck.
3. Rolling Friction
The rolling resistance for steel on steel is a paltry = 0.002. How long would it take a
500,000 kg train to come to a stop if it was originally rolling at 10 m/s?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc0e13850-687b-4b94-8359-e8984c789308%2Fad3e37a5-c8b6-4530-91fa-c4fedbb21157%2Fqrnvvwd_processed.jpeg&w=3840&q=75)
