A Force F is applied to block A (mass Ma)

1.Determine the acceleration of the system (in terms of Ma,Mb, & Mc)
2. Determine the net force on each block
3. Determine the force of contact that each block exerts on its neighbor.
4. If mA=mB=mC=12.0kg and F=96.0N, give numerical answers.
5. Do the answers make sense intuitively?

The range of a projectile depends not only on v0 and θ0 but also on the value g of the free-fall acceleration, which varies from place to place. In 1936, Jesse Owens established a world's running broad jump record of 8.09 m at the Olympic Games at Berlin (g = 9.8128 m/s2)) Assuming the same values of v0 and θ0, by how much would his record have differed ( in cm) if he had competed instead in 1956 at Melbourne (g = 9.7999 m/s2)?

I'm thinking turbulent air is a no no for aerodynamic efficiency, but does the highway's air actually move with the direction of traffic since the mass of vehicles is so massive? I imagine maybe it loops above the car masses as the cars push through. So I'm thinking there is maybe efficiency if you stick close to other cars. What do you think? What about behind big trucks? Not considering safety because this is just theoretical.

1. A radar antenna is tracking a saetellite orbiting the earth. At a certain time, the radar screen shows the satellite to be 162 km away. The radar antenna is pointing upward at an angle of 62.3 degrees from the ground. Find the x and y components (in km) of the position of the satellite.

2. The altitude of a hang glider is increasing at a rate of 6.8 m/s. At the same time, the shadow of the glider moves along the ground at a speed of 15.5 m/s when the sun is directly overhead. Find the magnitude of the glider's velocity.

Thanks...

I was wondering if it is possible to consider any real circle (say, that of a plate or a disk) to be measured in multiples of pi, since pi has infinite numbers after the decimal. Of course everything must have an exact length regardless of how many numbers after the decimal there may be, is it not so?

think about it every time you step up on a ledge to are building energy and when you come down you release the built up energy. The energy to do that comes from carbs that you burn, i guess what im asking is what is the simplest form of energy?

I am curious on other methods of slowing down the speed of time realitive to the observer. Like being on Jupiter would slow down time because of it 23 times Earths gravity so I suspect. Has anybody thought of sending a probe onto Jupiter to find out? I know aproaching the speed of light also slows down time too. Black holes would. Is there any other way to slow down time other then being in a crushing gravity well or being crushed by increasing velocity in a space ship.
Is there another way to slow down or to stop time completely. No video or sped up film for an answer. I think I have a solution to this problem but I need to ask if I anyone else has come up with an answer better then my own. Think about it.

So lets assume the pressure cooker uses a weight over a small opening in the lid. As the cooker heats up internal pressure increases until the weight is lifted slightly and the gas can escape.

If you know the mass of the weight, diameter of the lid and ambient air pressure...is it possible to figure out at what pressure gases will begin to escape from the cooker? (i.e., the weight gets lifted so gas can escape).
