In the system below the hanging mass of m and the mass on, Ask an Expert

Academics

In the system below, the hanging mass of M and the mass on the horizontal table top is m=200.0g. The pulley had negligible mass, and it is negligible. Tho coefficients of static and kinetic friction between m and the table top are 0.8 and 0.4, respectively.

1. What is the maximal value of the hanging mass M (in kg) so that the system remains stationary? Sketch relevant free body diagrams.

2. If the hanging mass is M=400.g and the system is in motion, what is the acceleration that the blocks have? Sketch the relevant free body diagrams and show all work. Don't forget that there is friction!
