A tank is filled with water to a height H, 26 m. A hole is punched in one of the walls at a depth h = 6.50 m below the water surface (see the figure). What is the distance x from the base of the tank to the point at which the resulting stream strikes the floor?
i knoe the equation to find out...
A swimming pool has dimension 23.0 m by 8.0 m with a depth of 3.0 m. When it is filled with water, what is the force (resulting from the water alone) on the bottom?
When it is filled with water, what is the force (resulting from the water alone) on each short side?
i figured out part a...

The density of a certain planet varies with radial distance as: D(r) = Do*[1-(a*r/Ro)], where Ro= 3.1623×106 m is the radius of the planet, Do = 3160 kg/m3 is its central density, and a = 0.160. Calculate the total mass of this planet.
Calculate the weight of a one kilogram...
Problem:
An engineer estimates that under the most adverse expected weather conditions, the total force on the highway sign in the figure below will be F = 2.48i - 2.88j kN, acting at the center of mass (CM).
Assume that L1 = 8.13 m and L2 = 6.45 m. What are the x, y, z components of the...
Recent studies have raised concern about `heading' in youth soccer (i.e., hitting the ball with the head). A soccer player `heads' a size 4 ball, deflecting it by 52.0°, and keeps its speed of 10.00 m/s constant. A size 4 ball has a mass of approximately 0.302 kg. What is the magnitude of the...
Your friend has just been in a traffic accident and is trying to negotiate with the insurance company of the other driver to pay for fixing her car. She believes that the other car was speeding and therefore the accident was the other driver's fault. She knows that you have a knowledge of...
nm i figured it out it's not v1initial = v1final + v2final
it's v1intial = v2final - v1final
*edit* okay i dunt get the 2nd part of the question though
What fraction of the original kinetic energy gets transferred to the second ball? Do not enter units
do i use 1/2m1(v1final)^2 -...
A 0.308 kg croquet ball makes an elastic head-on collision with a second ball initially at rest. The second ball moves off with half the original speed of the first ball. What is the mass of the second ball?
so i used the formula m1v1initial + m2v2initial = m1v1final + m2v2final
v2initial=0...
A thin rectangular plate of uniform areal density 2.96 kg/m2 has length 42.0 cm and width 26.0 cm. The lower left hand corner is located at the origin, (x,y)= (0,0) and the length is along the x-axis. There is a circular hole of radius 5.50 cm with center at (x,y)=(15.00,11.00) cm in the plate...
A 4350 kg rocket is traveling in outer space with a velocity of 126 m/s toward the Sun. It needs to alter its course by 24.8°, which can be done by shooting its rockets briefly in a direction perpendicular to its original motion. If the rocket gases are expelled at a speed of 2240 m/s relative...
