Question

A server at a diner slides a 0.521 kg root beer from the end of the counter to a thirsty customer. A force of friction of 1.32 N brings the drink to a stop right in front of the customer. What is the coefficient of kinetic friction between the glass and the counter?

Answer 1

F(fr)=μ•N=μ•m•g
μ=F(fr)/mg
