Amass weighing 20 pounds stretches a spring 6 inches. the mass is initially released from rest from a point 9 inches below the equilibrium position. (a) find the position x of the mass at the times t = π/12, π/8, π/6, π/4, and 9π/32 s. (use g = 32 ft/s2 for the acceleration due to gravity.)]

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
