A worker applied force, P to move a box at a construction site as shown in Figure. The box was resting on a floor that has a coefficient of static and kinetic friction of u, = 0.31 and ux = 0.22, respectively. The weight, W of the crate is given in Table (a)What is the type of friction acting on the box? Explain your answer. (b)Using the box as an example, explain what you understand about static and kinetic friction. (c)If P = 210 N, determine whether the box will move or not. If the box moved, determine the kinetic frictional force. (d)If P. = 425 N, determine whether the box will move or not. If the box will move, determine the kinetic frictional force. (e)Determine the minimum value of P that will make the box move. W=50kg
