Salmon swimming up a river to their spawning grounds, leap over all sorts of obtacles. The unofficial salmon-altitude record is a 3.56m jump. Assuming that the salmon took off at a 45 degree angle, what was the speed at which it was emerging from the water?
Xo = 0m
Yo = 0m
Y = 3.56m
a =...
These are the problems I have to choose between for a school project entering a competition. There are other problems but these are the ones I'm torn between.
Hydraulic jump
When a smooth column of water hits a horizontal plane, it flows out radially. At some radius, its height suddenly...
!urgently! long jump physics
I need the physics of the long jump. What happens between the start and the landing. I'll be grateful if you could apply formulas for the acceleration, speed, flight, etc. Thanks in advance :smile:
Alright, I have a question regarding quantum physics, but I don't want to post in that forum, because it scares me. I saw a website, it had an atom fill up electrons in orbital, as it got high, a rather unusual thing happened, an electron from an S orbital jumped to fill a P sub-orbital. I was...
need help helpme please i am going insane
The year is 2115. There is a high jump competition on planet Mars. An athlete of mass 72 kg who has been clearing a height of 2.44 m on Earth just the week before is competing here. What is the height this athlete can expect to clear in this...
hi all,
i am just wondering... if there is a guy has to jump off a small boat (u know... those have no engine, and etc... just a small wooden boat) which is stay stationary in calm water and is about to explode (for some reason... ). so yeh, that guy has to jump off the boat from one of the...
Well, I'm pretty sure this is impossible. But anyone have this proven. I need to try n prove this for my class. Any help is apperaciated. By the way, killer whales top speed is 13.5 m/s, he jumps out of the water at abotu a 45 degree andgle and the pier he jumps is 15 feet high and 10 feet long.
A Standing Vertical Jump. Basketball player Darrell Griffith is on record as attaining a standing vertical jump of 1.2 m (4 ft). (This means that he moved upward by 1.2 m after his feet left the floor.) Griffith weighed 890 N (200 lb).

I am stumped... very hard question:
"A 70.0kg woman does a bungee jump. The length of the bungee cord is 5.00m and it has a spring constant of 122.08 N/m. Assume the gravitational field strength is 9.81 N/kg.
a)What is the maximun distance the bungee cord will stretch and how far will the...
hi everyone! ok so i was doing my homework and i came upon this one problem which completely stummped me and so if someone could set me in the right direction i would be very thankful! here is the promblem: If a salmon swims sraight upward in the water fast enough to break through the suface at...

Suppose a boy is playing bumgy jump. When he jumps out and reachs the lowest bottom (instanteous at rest), there is zero K.E.
At that time, there is max. elelastic potential energy in the string. Which energy is changed to it(max. elelastic potential energy) :confused: ?
I have a theory it states that temples where constructed using a series’ of ramps and platforms between each temple column . Eventually creating a total square platform for the next layer of temple drums to be rolled into position . As the temple got higher the builder would jump from the...
The question of "jumping stones or halters". inscriptions on the jumping stones have been translated to halters .

Ok everyone I have a task for homework which asks me to: Determine the parameters for a rope suitable for you to use to make a safe 40m jump.
At the moment, I'm unsure of the physics behind bungee jumping, but I know the parameters that I'd have to consider would be the length of the rope...
Could someone help me set up this problem and give some helpful hints.
From what maxium height can a 75-kg person jump without breaking the lower leg bone on either leg? Ignore air resistance and assume the CM of the person moves a distance of .60m from standing to the seated position (that...
Hi,
I have a serious problem. My friend thinks she can jump off the moon. I know it's really dumb, but my classmates and I just can't convince her. Say like she's a baby, cause she's a moron. We even drew diagrams and pictures. Please help.
Hi guys, I'm new :smile:
Now, I came here in search of help to a homework problem I have. I've tried to solve for around 40 minutes now, and can't get past solving for k. Here's the problem.
The way I'm trying to solve is is by setting up two parts. One, I just solve for K in general...
The question is:
If a sprinter running at 10 meters per second could convert his
kinetic energy into upward motion, how high could he jump?
How do I solve this if I use the KE = 1/2 mv^2
I don't know what the mass is?
Hi my problem is that I have to model a bungee jump and enter it into a flowchart. I've worked out the free-fall part, but my problem is that the jumper has now reached the point where hookes law comes into play.
The jumper mass is 90kg
The unstretched length of the rope is 15m(of neglible...
I am having problems with this section. Any help is appreciated.
Salmon often jump water falls to reach their breeding ground. Starting 2 m from a waterfall .55 m in height, at what minimum speed must a salmon jumping at an angle of 32 degrees leave the water to continue upstream?
