A skydiver typically achieves terminal velocity within 10-15 seconds after jumping out of the plane. Terminal velocity is reached when the force of air resistance pushing up on the falling object equals the force of gravity pulling it down, resulting in a constant falling speed.

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.
What happens when a Skydiver Jumps Out Of A Hovering Helicopter So There Is Forward Velocity. What Is The Skydiver's Acceleration?
When a skydiver jumps out of a hovering helicopter with forward velocity, the skydiver's initial velocity will be a combination of the helicopter's forward velocity and the vertical velocity due to gravity. As the skydiver falls, their acceleration is primarily due to gravity acting downward, with air resistance also playing a role. The acceleration experienced by the skydiver will be constant at approximately 9.8 m/s^2 downward, ignoring air resistance.
When the skydiver steps out of the helicopter someone who's watching starts a stopwatch. So the time is zero as the skydiver steps out of the plane. What is the skydiver's downward velocity at that?
At the moment the skydiver exits the helicopter, their downward velocity is initially zero. As they fall due to gravity, their velocity will increase over time.
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.
What is a skydivers velocity after 2 seconds?
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.

How can a skier achieve greater velocity than a skydiver?
If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.

When a skydiver jumps out of a hovering helicopter so there is forward velocity. what is the skydiver's acceleration?
Initially, the skydiver will experience an acceleration due to gravity, which is approximately 9.81 m/s^2 downward. As the skydiver falls, air resistance will oppose this acceleration, causing the skydiver to reach a terminal velocity where the downward acceleration due to gravity is balanced by the upward force of air resistance.
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 are the forces acting on a skydiver?
The main forces acting on a skydiver are gravity, which pulls the skydiver downward, and air resistance (drag), which acts in the opposite direction of motion. As the skydiver falls, air resistance increases until it balances out the force of gravity, leading to a constant velocity known as terminal velocity.
Why is a skydiver's speed wont continue to increase until his or her parachute opens?
A skydiver's speed doesn't continue to increase because of air resistance, also known as drag force. As the skydiver falls, the force of air resistance increases until it balances out with the force of gravity pulling them downwards. This causes the skydiver to reach a terminal velocity, the maximum speed they can achieve while falling, before the parachute opens.
When does a skydiver have the greatest kinetic energy?
A skydiver have the greatest kinetic energy as he/she wants to hit the water.
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.
