What is the mass of a block of iron if a net force of 240n causes it to accelerate across a smooth surface at 2.5m/s^2?

According to newton's second law of motion F=ma

Explanation:

Data:-F=240N ,a=2.5m/sec² and m=? solution:-F=ma here we have to find m so m=F/a ,m=240/2.5=96kg

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
