When skydiver slows down from 54 meters to 4 meters by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
A skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydivers acceleration?
80 m/s2 up
A skydiver slows down from 54 ms to 4 ms by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydivers acceleration?
66.7 m/s2
What effect would opening a parachute have on a skydiver's fall?
Only if they have a heart attack, but not likely.
Skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
80 m/s 2 up
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
When a skydiver opens their parachute, air resistance increases which slows down the skydiver. Terminal velocity is the maximum speed a falling object can reach when the force of gravity is balanced by the force of air resistance. Opening the parachute decreases the skydiver's speed, allowing them to land safely.
What is the skydiver's downward velocity?
Maximum speed is about 220 to 230mph and can be achieved after about 20 seconds of freefall. Normal parachute opening speed should be not greater that 120mph to avoid damage to the parachute
What A skydiver slows down from 54 ms to 4 ms by opening his parachute this change takes 0.75 what is the skydiver acceleration?
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
A skydiver slows down from 54 m s to 4 m s by opening his parachute this takes 0.75 seconds what is the skydivers acceleration?
He will decelerate (meaning an acceleration in the direction opposite of current velocity) at a rate of (54 m/s - 4 m/s)/.75 seconds = 66.67 m/s2. This is about 6.8 Gs.
A skydiver slows down from 54 ms to 4 ms by opening his parachute. if it takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
(4 m/s - 54 m/s)/0.75 s = -50/0.75 m/s² = -200/3 ≈ - 66.67 m/s² (negative because he is decelerating)
Why a skyd Iver will fall with a constant speed after he open his parachute for a while?
A skydiver falls with a constant speed, known as terminal velocity, after opening their parachute because the force of gravity pulling them down is balanced by the drag force from the air resistance acting against their fall. Once the parachute is deployed, it increases the surface area, significantly enhancing air resistance. When these two forces equalize, the skydiver stops accelerating and descends at a steady speed. This balance between gravitational force and air resistance is what stabilizes the descent.
