Homework Statement Which is greater, the frequency of the Moon’s revolution about the Earth, or the frequency of Earth’s revolution about the Sun? How much (factor) greater? Homework Equations f=1/p p=period The Attempt at a Solution Earth= 1 Revolution/365 days (1 rev/31536000...

How would you find absolute with all of those, would you calculate the pressure of each layer, add them together and subtract atmospheric? Or is Atm. not in it already?

Homework Statement A creamy salad dressing is made up of heavy cream, corn oil, and vinegar (as well as a pinch of dry mustard, salt and pepper). You put the cream, oil, and vinegar in a glass jar. The density of the cream is 994 kg/m3, the oil 880 kg/m3, and the vinegar 1000 kg/m3. The...

That Momentum is always conserved

Homework Statement Consider a head-on collision between two people. The damage done to each person is far greater if the people rebound upon impact versus sticking together upon impact. Why? Discuss in terms of impulse/change in momentum. Homework Equations Momentum = (mass x Volume...

We are not doing momentum yet

Other than that do I do the same thing I did? And would the rackets acceleration be negative?

Could you explain how I should go about this? Our physics teacher was gone all week and could not help us.

Homework Statement A tennis racket (950 g) hits a tennis ball (110 g) with a force of 5000 N. What is the acceleration of the tennis ball? During the collision, with what force does the tennis ball hit the tennis racket? What is the acceleration of the tennis racket? (Remember that force...

That still doesn't help much.

Here, it is attached.

I am sorry, I thought it uploaded, one moment.

Yes, because the initial velocity of both would be 0 m/s and gravity would at equally on them both at -9.81 m/s^2 so at the same time they would have the same speed.

Homework Statement Harry the painter swings year after year from his bosun’s chair. His weight is 575 N and the rope, unknown to him, has a breaking point of 300 N. Why doesn’t the rope break when he is supported as shown at the left below? One day Harry is painting near a flagpole, and...
