1. A miner strikes what he thinks is a lead vein. To be sure it is lead, the miner checks it's density. The metal has a mass of 12 grams and occuples a volume of 3cmº. Calculate Its density.​

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
