you push horozontally on a 120 n box that is initially resting on a horizontal table. the coefficient of static froction between the table and the box is 0.75 and the coefficient of kinetic friction os 0.40. find the friction force on the box if the push was equal to 84 n.

Plss anybody know how to do this? ? i need the answers from a through d
