The speed of a skydiver after 5 seconds of free fall can be estimated using the formula for velocity under the influence of gravity, accounting for air resistance. In free fall, a skydiver accelerates at approximately 9.8 m/s², but due to air resistance, they reach a terminal velocity. After 5 seconds, the skydiver's speed would be around 40-50 m/s (approximately 90-110 mph), depending on their body position and weight.

If a skydiver reaches terminal speed after ten seconds will the skydiver gain more speed during the first second or the ninth second?

I would imagine that it is uniform acceleration up until terminal speed. However, wind resistance will be higher 10000 feet up, so acceleration may be less at the start


When a skydiver has reach the terminal speed what is the air resistance equal to what is the sky diver acceleration?

When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.


How fast is a skydiver after falling 3 seconds if they accelerate at 10 meters per second?

The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.


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.


Why is a skydiver not in freefall?

A skydiver is not in freefall when they have opened their parachute. The move from free-fall to controlled decent under a wing.


Why does a skydiver loose speed when he opens his parachute?

A skydiver loses speed when he opens the parachute because the parachute creates drag by slowing down the movement of air. This drag force opposes the motion of the skydiver, causing a decrease in speed. Additionally, the larger surface area of the parachute increases the effect of air resistance on the skydiver's body.


How fast does a skydiver fall?

Speed during free fall can change depending on a skydiver's size and body orientation. In the belly to earth orientation, the speed is about 120 mph. If the skydiver is wearing a wing suit, their vertical speed could be as low as 60 to 70 mph. In a head down orientation, the speed can often be greater than 200 mph.


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.


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.


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.


Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?

No.Acceleration is a measure of the rate of change of velocity (speed & direction). If acceleration is decreasing (but still above zero) then this means that the rate at which the speed is increasing in this direction is decreasing.As long as the downward acceleration is greater than zero then the skydiver's speed is still increasing.Once terminal velocity is reached then downward acceleration will equal zero (speed is constant).If the downward acceleration falls below zero (as will happen once his parachute is deployed for instance) then this means he is slowing down.


Is the skydiver increasing or decreasing his speed during the first 3 seconds?

Increasing.
