So I got that I would have to get the weight above water, and then get the weight when it is submerged in water and the force would equal the weight difference. How do I get the weight underwater?

Homework Statement Create a lab that proves the buoyant force equation; on a separate sheet of paper That is the directions Homework Equations F = pvg The Attempt at a Solution We haven't done anything to do with buoyancy, this is extra credit. I'm not sure what to do.

Homework Statement A boat, which can travel at 8.2 m/s in still water, heads directly across a river which has a current of 4.5 m/s and is 477 meters wide. What should the heading of the boat be in order for it to land at a point on the opposite shore exactly 100 m upstream from the starting...

Hi, This isn't a homework question. I need help on how to go about solving 2D kinematics problems. My teacher is terrible and doesn't even teach. It seems like it should be pretty straight forward with solving these, but I'm just having a hard time. If someone could give me tips on how to...

Not sure. Can you please explain?

Homework Statement A car is initial at rest. It accelerates over a distance of 1250m and reaches a speed of 112 km/h. Find: A) the acceleration for the car B) the time it took for it to reach this final speed C) the average speed Homework Equations A = delta V/ delta T or v^2 = V...

Homework Statement A ball is thrown straight up. If its initial velocity is 24m/s, how high does it rise before it begins falling down? Homework Equations The Attempt at a Solution This one is very frustrating to me. My teacher doesn't teach us, he just gives us the homework and...

I got 2975.28 m/s, but I am not sure if that is correct.

So we are looking for speed, right?

Or are we looking for velocity?

What is the value for initial velocity? V= 53.9 m/s^2 A= 53.9m/s^2 T= 55.2s S= ? I got distance as 2975.28 but I don't know if that is correct

Could you help me work it out?

What is u? v is velocity, a is acceleration, and t is time, but what is u?

Homework Statement The space shuttle undergoes an acceleration of 53.9 m/s^2. How fast is it traveling at the end of 55.2 s? Homework Equations The Attempt at a Solution I have no clue. I am doing a summer assignment and it is very poorly explained by the teacher.

You nose out a runner to win the 100 meter dash. If your total time was 11.8 seconds and you won by .001 seconds, by how many meters did you win? Help! Thanks!
