A 950-N skydiver jumps from an altitude of 3000 m. What is the total work performed on the skydiver?
Work is the force times distance, so the answer is 2,850,000 joules.
What else can I help you with?
On a perfect fall day you are hovering at low altitude in a hot-air balloon accelerated neither upward nor downward The total weight of the balloon is 17500?
The buoyant force exerted by the air on the balloon must be equal to the weight of the balloon in order to maintain a constant altitude. This means that the buoyant force is 17500 N and it is balancing the weight of the balloon. If the buoyant force decreases for any reason, the balloon would start to descend.
What is the skydiver's average velocity for the first 3 seconds?
14.715 m/s. This is worked out by knowing that gravity will accelerate a body at 9.81 (m/s)/s. The average velocity is the speed at 3s plus the speed at 0s divided by 2. Speed at 0s = 0 x 9.81 = 0 m/s Speed at 3s = 3 x 9.81 = 29.43 m/s (29.43 + 0) / 2 = 14.715 m/s.
Speed of human skydive free fall?
You can find this by starting the person, from rest, at an infinite distance from the earth, where the force of gravity is essentially zero, but just enough to start the person falling. By using the correct equations for gravitational potential energy and kinetic energy the total energy at that location is zero. As the person falls he gains kinetic energy and losses potential energy so the total remains zero (conservation of energy) and you can show when he hits the earth his maximum velocity will be 11,000 meter/s (that's approximately 24,000 miles per hr.). His actual velocity will be less because of air resisatance. This is the same velocity that a projectile (like a bullet) must , At Least, have to escape the earth's gravity, when fired out into space.
What equation do you use to find average speed?
The equation to find average speed is total distance traveled divided by total time taken. Average speed = total distance / total time.
What is a natural example of total internal reflection?
If you look at the surface of the water in an aquarium from the side of the aquarium with your eyes just below the level of the water, it will look like a mirror, and you won't be able to see anything above the surface. That's also true of a glass of water, but you can see the effect much more clearly with a container as large as an aquarium. Just make sure nobody jumps around or bumps into the aquarium or the table it is on because those vibrations will result in small waves in the water's surface and it won't look as good.

TheI momentum of a skydiver increases as speed increases does the momentum of the earth simultaneously change how much and in what direction how does the system made up of the earth and the skydiver?
For a simple answer, we have to ignore air resistance. As the skydiver's downward momentum increases, the earth's upward momentum increases by an identical amount. The total momentum of the earth-skydiver system remains constant.
How long does it take to freefall 12000 ft?
The time it takes to freefall 12,000 feet depends on several factors, including the skydiver's body position and the effects of air resistance. Generally, a skydiver in a stable belly-to-earth position can expect to reach terminal velocity at around 10-12 seconds, falling the full 12,000 feet in approximately 30-40 seconds total, including the time to accelerate before reaching terminal velocity. However, if the jump is from a higher altitude or involves a parachute deployment, the timing may vary.
How much air resistance acts on a 500 N skydiver that falls at her terminal velocity?
500 N is pressumably the weight, due to gravity. "Terminal velocity" means that the forces are in balance; the total force acting on the skydiver are zero. This is only possible if there is a 500 N force due to friction, to counteract the weight.

A skydiver started his jump from the airplane. He fell 4.9 m in the 1st second, 14.7 min the 2nd second, 24,5 m in the 3rd second. How far did he fall between the 7th and the10th seconds?
The skydiver fell a total of 94.4 meters between the 7th and 10th seconds. This was calculated by adding the distance he fell in each second (4.9 + 14.7 + 24.5 + 34.3 + 44.1 + 53.9 + 63.7 = 94.4 m).
How long is the course in a Olympic steepleache?
The Olympic steeplechase is a race that covers a distance of 3,000 meters (approximately 1.86 miles). The course includes barriers and water jumps, adding to the challenge of the race. Athletes must navigate a total of 28 barriers and seven water jumps throughout the distance.
