You are helping a friend moving to the 25th floor of an apartment building. You and your friend are loading on the elevator one of her large moving boxes, having a mass of 25.0 kg. As the elevator is accelerating upward with an acceleration of 3.80 m/s2, you push horizontally on the box. What is the magnitude of the force you should apply so that the box will start to move? Once it began to move, what force magnitude would you need to make it slide at constant speed? The coefficients of friction between the box and the elevator floor are μs = 0.64 and μk = 0.32.
