What else can I help you with?
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
A skydiver who weighs 500 N reaches terminal velocity of 90kmh the air resistance on the diver is then?
The air resistance on the skydiver at terminal velocity is 500 N. At terminal velocity, the air resistance on the skydiver is equal in magnitude to the gravitational force pulling them downward. This balance of forces results in a constant velocity.
When does a skydiver achieve terminal velocity?
A skydiver typically achieves terminal velocity, the maximum velocity at which they fall through the air, within 10-12 seconds of jumping out of the plane. This usually occurs at around 120 mph (193 km/h) for a skydiver in a belly-to-earth position.
How will an updraft and a downdraft affect a skydiver in reaching terminal velocity?
An updraft can slow a skydiver’s descent by providing lift, which counteracts the force of gravity and delays the attainment of terminal velocity. Conversely, a downdraft increases the downward force, potentially accelerating the skydiver to terminal velocity more quickly. The overall impact of these air currents can create fluctuations in the skydiver's speed and stability during free fall. Ultimately, terminal velocity is reached when the upward and downward forces balance out, regardless of these drafts.
What direction is the net force on a falling skydiver before she reaches terminal vilocity?
The net force on a falling skydiver is directed downwards, which is the force of gravity acting on the skydiver. This force causes the skydiver to accelerate as she falls until she reaches terminal velocity.
what force is increased after the skydiver open parachute?
To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.
Is a skydiver increasing or decreasing his speed during the first three seconds?
A skydiver is increasing their speed during the first three seconds of free fall due to gravity pulling them downwards. As the skydiver falls, their speed will continue to increase until they reach terminal velocity.
What happens to a skydiver before they open their parachute?
They jump out of the plane and accelerate to terminal velocity.
What shape what is the displacement versus time for the skydiver be?
The shape of the displacement versus time graph for a skydiver would be a curve that starts at zero displacement when the skydiver jumps out of the plane, increases as the skydiver falls accelerating due to gravity, and eventually levels off as the skydiver reaches terminal velocity. The curve will then be a straight line at a constant displacement representing the terminal velocity until the skydiver opens the parachute, at which point the displacement will decrease as the skydiver slows down and lands.
What is the net force on a skydiver with weight of 25N at the point he reaches terminal velocity?
At terminal velocity, the net force on the skydiver is zero. This occurs because the downward gravitational force, which is equal to the weight of the skydiver (25 N), is balanced by the upward drag force due to air resistance. As a result, the skydiver falls at a constant speed without accelerating.
When a sky diver reaches terminal velocity what happens to the two forces of weight and drag?
When a skydiver reaches terminal velocity, the force of weight acting downwards on the skydiver is equal to the force of drag acting upwards. This means that there is no net force acting on the skydiver, resulting in a constant velocity rather than acceleration.
