)a block is on a frictionless table, on earth. the block accelerates at 5.3 m/s 2 when a 10 n horizontal force is applied to it. the block and table are set up on the moon. the acceleration due to gravity at the surface of the moon is 1.62 m/s 2. a horizontal force of 5 n is applied to the block when it is on the moon. the acceleration imparted to the block is closest to: 3) a.3.4 m

When horizontal force is applied on block then as per Newton's II law we will have

so here mass will be

now on same block F = 5 N is applied on surface of Moon

so on surface on moon we will have

so above is acceleration on surface of moon

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
