A pipe with a diameter of 2.88 cm is carrying 134 liters/minute of water with an overpressure (gauge pressure) of 3.65 atmospheres. The pipe carries the water to the top of a three story apartment building with a height of 12.2 m, where the pipe is constricted to a diameter of 1.56 cm. Find the overpressure of the water in the pipe at the top of the building (assume no viscosity in this problem).
What speed limit should be posted for the curve. How long (in {rm ns}) does it take light incident vertical to the glass to pass through this 9.0 {rm cm}-thick sandwich.
The coefficient of kinetic friction is 0.400. Illustrate what should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?
A golfer tees off on level ground, giving the ball an initial speed of 38.5 m/s and an initial direction of 36.0° above the horizontal. (a) How far from the golfer does the ball land? (Neglect air resistance.)
An 10m, 210N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.55, and the ladder makes a 50° angle with the ground. How far up the ladder can an 850N person climb before ladder b..
Styrofoam has a density of 300 kg/m^3. What is the maximum mass that can hang without sinking from a 40cm diameter Styrofoam sphere in water? Assume the volume of the mass is negligible compared to that of the sphere.
A small 15{rm g} bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and can rotate freely, without friction.
