thanks, it would have helped, but i finally figured it out myself :) you are correct sir in your help

Yes but it's not giving me the right answer, is there another way to go about this problem?

3. a) least force on the road because as it is going up, it has a magnitude upwards taking away from g, the inertia makes the car want to keep going up reducing the weight on the road b) greatest force because the magnitude will be aimed downards and because of inertia, it has more force on...

Two different simple harmonic oscillators have the same natural frequency (f=2.80 Hz) when they are on the surface of the Earth. The first oscillator is a vertical spring and mass, the second is a pendulum. If both systems are moved to the surface of the moon (g=1.67 m/s2), what is the new...

if a bucket is on an elevator floor in a inconpressible fluid of density p. When the elevator is accelerating downards, what is the pressure difference between two points in a fluid, separated by a vertical distance of delta h. I was thinking that it is p (g - a) delta h, since it should be...

why 10 for g, isn't g 9.8 and where does the 50 kg's come from

I have a multiple choice question where a rock weighs 1400 N in air and 900 N apparent weight in fresh water with 998 kg/m^3 density (i think), The question is what is the volume of the rock. 2 of the choices are .14 m^3 and .051 m^3. I have tried p = m / v and 1400 - 500 and division by g's...

So the answer best answer would be 2 pi sqrt ( L / a )? Another similar problem is a bucket of a incompressible fluid of density, sitting on the bottom of an elevator accelerating downward with magnitude a, what is the pressure difference between the two points, separated by delta H i...

the question for the first one is really , 16,000 N of water are displaced by a boat, how many Newtons of saltwater is displaced with a specific gravity of 1.17 and for the second one, are you absolutely positive it's g + a, beause on another post i found in the K - 12 section they had it...

Are you sure it's 2 pi ( sqrt ( L / (g - a ) ) ? Or is it g + a?

I have 3 ideas that i am stuck on, 1. If you have water displaced in Newtons by a floating object, is the Newtons displaced of oil or any other liquid, what is the equation to find this. I tried many equations with densities and bouyant forces, but i can't seem to get the right answer, i was...
