Pushing and rolling physics question?
Hi, can anyone help me with this step by step?
A person with mass 60kg standing on a horizontal force is pushing a large wheeled crate of mass 800kg which can roll on same horizontal floor with coefficient of rolling friction 0.03. What is the minimum coefficient of friction required between the soles of the person's shoes and the horizontal floor if the person is to succeed in keeping the crate rolling at a constant speed without slipping? Assume both are dynamic equilibrium.
Thank you!!
The minimum force, F required to keep the wheeled crate rolling at constant speed is given by
F = 0.03x800x9.8 = 235.2 N
Then crate must apply the same force on the man in opposite direction so the floor must apply the force on the man in the opposite direction. Let the coefficient of friction between man's soles and floor be k, then for minimum value of k, we have
k x 60 x 9.8 = 235.2 or k = 0.4. If the coefficient of friction is less than 0.4 then man would slip and if it is more there is no problem. It will generate the required force.
