Yes the molecules
are all compressed together
The formula for working out speed is distance ÷ time.
55 km ÷ 2 hours = 27.5 km/h (average speed for first part of journey)
52km ÷ 5 hours = 10.4 km/h (average speed for second part of journey)
(27.5 + 10.4) ÷ 2 = 18.95 km/h (average speed throughout the journey)

Answer:3.98cm
Explanation:
given data
mass of object
=0.5kg
intial extension=5 cm
elevator acceleration=2 m/
From FBD of intial position
Kx=mg
K=
k=98.1 N/m
From FBD of second situation
mg-k
=ma
k
=m(g-a)
=
=3.98cm
