A30 kg wooden box sits on a smooth concrete floor.
the coefficient of static friction between the box and the floor is 0.35.
the coefficient of kinetic friction between the box and the floor is 0.23
1) how much force does the box exert on the floor? what is the equal and opposite force?
2) how much force, pushing the box parallel to the floor, is required to get the box moving?
3) how much force is required to keep the box moving at a constant velocity across the floor?
4) draw a completely labeled free-body diagram of the box while it is being pushed at a constant velocity along the floor.
5) assume the force required to start the box sliding is maintained as a constant force for 10 seconds. how fast will the box be going?

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s. t.p.?
