Document Summary
Phya10 practical week 5: a 5 kg box sits on top of a 7 kg box, which is itself on a table. The bottom box is pulled with a force f and starts to move as a result. The coe cient of static friction is 0. 4 everywhere, and the coe cient of kinetic friction is 0. 1 everywhere. Begin this question by drawing the free body diagrams for each box and clearly label any and all pairs of forces which correspond to. Newton"s third law: each room has a mass attached to an approximately 1 m length of string. (a) suppose one member of your group stood still and held the mass by their side. After you have made your predictions, take the mass and string and verify them. If everything is ideal (so the rope has a single tension everywhere, no friction in the pulleys, etc.
