Rain is falling at the rate of 2.3 cm/h and accumulates in a pan. Water has a mass of 1.00 × 10^3 kg per m^3.
If the raindrops hit at 8.3 m/s , estimate the magnitude of the force on the bottom of a 1.0-m^2 pan due to the impacting rain which we assume does not rebound.

If we combine the downward force of gravity with the upward buoyant force, we get what is known as the apparent weight of the object, Wapparent = mobject9 – Fbuoyant = PobjectgVtotal – Poutside gVdisplaced · For our experiment this week, we will be looking at a mass submerged in water. The apparent weight will be the weight force due to gravity minus the buoyant force due to the surrounding water. Consider the setup to the right with an object...

Water is flowing through a 10-cm diameter water pipe at a rate
of 0.2 m^3/s. Now a diffuser with an outlet diameter of 20 cm is
bolted to the pipe in order to slow down water that exits into the
atmosphere, as shown. Disregarding frictional effects, determine
the force exerted on the flange due to the water flow. Density of
water = 1,000 kg/m^3.

A 90 kg man stands in a very strong wind moving at 12 m/s at torso height. As you know, he will need to lean in to the wind, and we can model the situation to see why. Assume that the man has a mass of 90 kg, with a center of gravity 1.0 m above the ground. The action of the wind on his torso, which we approximate as a cylinder 50 cm wide and 90 cm long centered...
