You have just had the apples in your orchard harvested into a large number of boxes with masses of 134 kg each. You wish to lift these boxes 15.0 m up to the fourth floor of your packaging facility. Since you have only one person to help, you construct a slippery surface that is inclined 30° above the horizontal, and then fix a pulley at the top corner as shown in the figure below. You hang from the rope at the top of the incline and let the force of gravity pull the crates up the ramp. The friction between the crates and the inclined surface is negligible.

Cont: (Assume that the ramp is high enough above the ground that you touch the ground only when the mass has reached the fourth floor.) How long will it take to lift one crate to the fourth floor if the mass is 69.11 kg?
