Hi so I need to finish a report on our boat project that we had a day ago. How would I calculate the safety margin for my boats sides including waves and tilt expected and also the height of center of gravity of the person inside- Person inside weight: 160lbs Boat; Length is 3 ft 5 inches boat...

A fisherman and his young niece are in a boat on a small pond. Both are wearing life jackets. The niece is holding a large helium filled balloon by a string. Consider each action below independently and indicate whether the level of the water in the pond, Rises, Falls, is Unchanged or Cannot...

blocking the road.? The SUV slowed down at a constant rate of 4.0 m/s2 for 3.6 s before reaching the tree. a.What was the initial speed of the SUV? b.With what speed does it strike the tree? please help.. thank you in advance

Two 6.0 cm diameter (circular) electrodes are spaced 5.0 mm apart and charged. The charge on the positive plate is +1nC and the charge on the negative plate is -1nC. An electron is released from rest at the surface of the negative electrode. (assume the space between the electrodes is a...

The maximum transverse displacement of the string from its equilibrium position is 5 cm. At a fixed instant in time, the distance between two points where the string has zero displacement from its equilibrium position is 40. At a first position along the string, you observe that the string has...

Any ideas what questions may come in tomorrows ISC physics paper2??

I'm not the best at math and am just now getting into Geometry, so I'm tad behind but I'm still determined to learn and I would like to know what all mathematics I will need to get good at and what websites would help with all of this. Thanks.

I push a 10 kg crate from rest up an incline plane. The plane is 5m long and makes an angle of 25 degrees with the ground. (a) if I lose 100 J of energy to friction sliding the box to the top, how much work is required to push the crate to the top of the incline? (b) What is the ideal mechanical...

It's the age-old question. What's going to get you less wet, sprinting through the rain or walking normally? There are a lot more factors involved than you might have thought, but physics dictates that running as fast as possible will normally keep you drier, unless there's a tailwind, or, err...

In search of a different perspective on the physics of cancer, Princeton University and University of California, San Francisco researchers teamed up to use game theory to look for simplicity within the complexity of the dynamics of cooperator and cheater cells under metabolic stress conditions...

0.62 kg. Starting from rest,? A person with a blackbelt in karate has a fist that has a mass of 0.62 kg. Starting from rest, this fist attains a velocity of 9.0 m/s in 0.15 s. What is the magnitude of the average net force applied to the fist to achieve this level of performance?

I'm making a poster for extra credit and was looking for ideas. It's like a fan poster so it should be motivational while also involving physics? Anyone have any ideas? Thanks! :)

...Willing to sell your lab reports? Has anyone taken a physics II course through distance learning and used a LabPaq PK-2 or PK-S?!? Would you be willing to sell your lab manual and/or reports?

Science journal? I have been asked to write an article that will be printed in a science journal. The article should be on an interesting topic about physics. Teachers, professors as well as students participating in a national Physics Olympiad will be reading this; so it has to be catchy about...

Please help: Book Sci-fi Horror physics Soldiers go into a haunted house which turns out to exist in other dimensions so there are creatures not from this earth who try to east them or kill them. They can't escape, the doors lead to other places in the house. In the beginning there is a...

Hey, I am in a college level physics course that is calculus based. In my class I have to write a 2 page paper and give a short presentation on any topic of my choice. I wanted to do Chaos Theory but my instructor said that is more mathematically based and he would prefer something more...

So, for a physics project we have to find examples of projectile motion and use images to make a collage. I'm trying to think of examples of projectile motion in karate. I know it's not traditionally thought of, but I think there are some. Examples: -Throwing a nunchuku -Hitting a moving target...
