Question: Liza and 4 friends need to move five 30 kg boxes to a platform 8 m high, as fast as possible. A ramp with an incline of 10° leads up to the
platform, meaning that the ramp is about 45 m long. Additionally, a pulley dangles above the platform and could easily accommodate a
length of rope in the trunk of Liza's car. How would you recommend Liza and her friends move the boxes? Be sure to consider the effort
force required for your solution and the time required to complete the task.
