Question

A friend’s car has run out of gas and four of you are pushing the car to the gas station at a constant speed of 4.5 km/h. If two of you are pushing with a force of 300 N and the other two are pushing with a force of 425 N, what is the force of friction between the car tires and the road?

F(fr)=ΣF=300•2 +425•2=1450 N
