Atruck accelerates uniformly from rest to a speed of 9.2m/s over a distance of 26.2 m. determine the acceleration of the truck.

1.62m/s^2

Explanation: Using V^2=U^2+2a*s

V=9.2m/s, U=0, d = 26.2m

V^2=2a*s

a = V^2/2s

a = 9.2^2/2*26.2

a = 1.62m/s^2

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

the closer the planet is to the sun, the larger the gravity
