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?
A skydiver typically falls at a speed of about 120 mph (193 km/h) during freefall due to gravity. This speed is known as terminal velocity, when the force of air resistance balances the force of gravity acting on the skydiver.
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?
A skydiver's speed doesn't continue to increase indefinitely because of air resistance, which creates a "terminal velocity" where the force of air resistance balances the force of gravity. As the skydiver falls faster, air resistance increases until it matches the force of gravity, resulting in a constant speed.
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
Yes, if the acceleration of the skydiver decreases as falling progresses, it means the skydiver is slowing down. This indicates that the force of gravity pulling the skydiver downward is being countered by air resistance, causing the skydiver to decelerate.
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.
A skydiver slows down from 65 m s to 5 m s by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
The general formula for acceleration is [(final velocity) - (initial velocity)]/(time required for the change). In this instance, (5 - 65)/0.75 = -80 meters per second per second.
