A skydiver loses which type of potential energy as she falls?
She loses gravitational potential energy.
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.
As a skydiver fallsthe air is forced around him.what energy transformation doe's this cause?
Gravitational potential energy of the sky diver to kinetic energy of the air which moves around him.
What energy does a skydiver lose as they fall?
Potential energy.
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 skydiver's acceleration?
66.7 m/s2

She loses gravitational potential energy.
Are people weightless in the air?
No. Things are only weightless in the absence of a gravitational field or in constant acceleration (Inertial weight or mass) (Ask any skydiver.)

zero

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!
What energy does a skydiver lose as they fall?
Potential energy.
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.

66.7 m/s2
If a skydiver jumps out of an airoplane how much gravity is hitting him?
Exactly the same as hits a passenger sitting comfortably in another airplane at the same altitude:A downward force called his "weight", and a downward acceleration of 9.8 meters per second2.
Are the forces balanced or unbalanced when a skydiver is accelerating downward?
An acceleration requires an unbalanced force.
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.
