The first thing that I did was calculate the momentume of each shape before the collisions. To find the momentum
before the collision I used thew equation p=m*v. Using
this equation I found the momentums for the triangle and
the circle. For the triangle the before momentum
was(2kg)*(4m/s) = 8kg*m/s and the circle was (6kg)*(4m/
s) =24kg*m/s. With those two shapes coliding I had to add
both of those numbers together and it would be 32kg*m/s.
Next, I used the momentum equation (p=m*v) to figure out
who's speed was found AFTER the collision which was
(32-24)= 8kg*m/s. Since the momentum before was
32kg*m/s. I subtracted the total by the circle before and
the circle after thr collision. Finally I usesd the
momentum equation, solved for v (p=m*--> v=p/m) to
determine the velocity of the circle after the collision

-I want this re-worded but similar

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
