Question

a parachutist drops freely from an aeroplane for 10 seconds and then the parachute opens out. then he decends with a net retardation of 12 m/s^2 . if he strikes the ground with a velocity of 20 m per second then the height at which he gets out of the plane is

Answer 1

given,
for approximate value take g =10m/s²
we got 900m
but this is approximate
if ,g = 9.8m/s²
height = 890m

Answer 2

Answer:

• 873.5 is your correct answet
