What else can I help you with?
A person jumps off a diving board 4.0m above the water's surface into a pool the person's downward motion stops 2.0m below the surface of the water estimate the avg. decleration of the person under wa?
so what you need to do is find the velocity that the person enters the water and then use the equation v sub final squared = v sub initial squared + 2*acceleration(final distance-initial distance). final velocity is zero, find the initial velocity yourself and use 2 as the final distance where the initial distance is 0, solve for acceleration. Easy way: the decelleration would have been twice that provided by gravity because the diver decellerated to zero in half the distance of the dive. The diver starts at zero and hits max velocity in 4 meters then goes from max velocity to zero in 2 meters. 2 x 9.81 m/s2 = ___
Formula for accleration?
There are several formulae that involve acceleration. The most basic one is the definition of acceleration, which is: a = (difference in velocity) / time This assumes constant acceleration. For non-constant acceleration, the more general formula is: a = dv / dt where "dv" is the difference in velocity, and "dt" is the time interval, with the additional assumption that it is a very small time interval. For more details, read an introductory calculus book, to understand the concept of "derivative".
Examples of terminal velocity application to human.?
Terminal velocity is the maximum constant speed that a human can reach when freefalling through the air, typically around 120 mph when in a skydiving position. Understanding terminal velocity is crucial in activities like skydiving and bungee jumping as it ensures a safe and controlled descent. By reaching terminal velocity, the force of air resistance acting on the falling human balances out the force of gravity, leading to a constant speed.
Is a diving board a incline plane?
No, a diving board is not an inclined plane. An inclined plane is a flat surface that is tilted at an angle, whereas a diving board is a raised platform used for diving into a pool that is supported at one end.
What kind of energy is used when diving?
When diving, energy from food stored in the body is utilized by the muscles for movement and breathing. Additionally, the body may also use energy stored in the form of glycogen and fat to sustain prolonged diving activities.
When a person steps off a 12 foot diving board with 0 intitial velocity how many seconds does it take to reach the water?
0.8633 seconds
What must be the initial velocity of super boy to catch a package dropped from the top of a 56.0m high building 56.0m and 2 seconds later super boy dives off the building to catch the package?
Diving is generally taken to mean that you start from rest and jump. If Superboy dives off the building, he would initially have had zero velocity, relative to the building.

How do you clear a head cold before scuba diving?
hold youre breth for 10 seconds
Does Suriname have scuba diving?
Scuba diving really hasn't been developed in Suriname. The only diving site that's listed is the wreck of the German cargo ship 'Goslar' in the Suriname River. Its geographic coordinates are 5 degrees 49 minutes 5.32 seconds North latitude and 55 degrees 9 minutes 32.84 seconds West longitude.
Can ducks dive?
Yes, ducks are capable of diving underwater to forage for food. They use their webbed feet to paddle and their wings to help maneuver while swimming. Some duck species, like the diving ducks, are particularly skilled at diving and can stay submerged for up to 30 seconds.
Real-life example of free fall?
Technically not real free-fall, but close enough to put the point across: -- jumping or diving from the high board at the pool -- the first several seconds of sky-diving -- the 'vomit comet' aircraft that flies parabolic arcs and gives its passengers, such as astronauts in training, several seconds of weightlessness.
Do human body break apart from high velocity impact against a wide smooth surface for example sky diving accident?
yes whit out a parashoot

Is sky diving an example of free fall?
It is, until terminal velocity is reached. That is when the air resistance is equal to the force of gravity, thus you don't accelerate any more.
Janet runs horizontally off a high-diving platform and lands 1.95 m from the edge of the platform If the diving platform is 4.00 m above the ground at what velocity did Janet run horizontally?
Please answer soon! I need to know by tomorrow. Thanks. The answer is 2.17 m/s.
How much would it cost per year to have your own diving equipment?
After the initial purchasing costs of scuba diving equipment, maintenance and inspection cost can run you anywhere from $35 to $100 dollars a year. Snorkeling gear will cost you much less to maintain per year.
