- A makeshift sign hangs by a wire that is extended over an ideal pulley and is wrapped around a large potted plant on the roof as shown in Figure P6.10. When first set up by the shopkeeper on a sunny and dry day, the sign and the pot are in equilibrium. Is it possible that the sign falls to the ground during a rainstorm while still remaining connected to the pot? What would have to be true for that to be possible?

You then load up the pickup and pump up its tires so that its total weight increases by 42%while the coefficient of rolling friction decreases by 19%. Now what horizontal force will you need to move the pickup along the same road at the same speed? The speed is low enough that you can ignore air resistance..arrow_forward

F This force can either push the block upward at a constant velocity or allow it to slide downward at a constant velocity. The magnitude of the force is different in the two cases, while the directional angle e is the same. Kinetic friction exists between the block and the wall, and the coefficient of kinetic friction is 0.300. The weight of the block is 57.0 N, and the directional angle for the force F is 0 = 35.0°.
