A lightweight diving board is supported by two pillars. One is at the end of the board and the other is 1.30 m away. A 75-kg person is standing on the board at such a location that the pillar at the end (pillar #1) of the board exerts a 850-N force downward. Determine the following.(a) distance the person is standing from the end pillar (pillar #1)(b) magnitude of the upward force exerted by the second pillar (pillar #2)

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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
