Question:
You are controlling the descent of two crates that are sliding down a sloping floor, as shown in the figure.(Figure 1) You pull on a rope parallel to the sloping floor. The top crate sits atop the lower, and both boxes move together at a constant speed of 17.0 cm/s . The coefficient of kinetic friction between the slope and the lower crate is 0.478, and the coefficient of static friction between the two crates is 0.807.
a. What force T do you need to provide so that the crates move at constant velocity?
b. What is the magnitude f of the friction force on the upper crate?
