a skydiver jumps from a high-flying helicopter
as she falls faster and faster through the air , does her accerlation increse, decrease , or remain the same
Answers
acceleration remain the same when skydiver Falls faster and faster through the air
Explanation:
g = GM/R²
g = acceleration due to gravity
G - gravitational Constant
M - Mass of Earth
R = Radius of Earth ( if object is at ground)
or Distance of object from Center of Earth
As Sky Diver jump initially
R = Radius of Earth + height
height keep Decreasing as sky diver comes down
Hence R keep reducing
so g will keep increasing
but Radius of Earth = 6400 km & height of skydiver hardly 3-4 km
which is negligible compared to radius of earth
Hence increase in acceleration will Be negligible
also the atmospheric pressure increase with decrease in height and that will oppose the acceleration due to gravity
Hence over all there would not be any significant impact on acceleration
Hence we can say acceleration remain the same when skydiver Falls faster and faster through the air
