What is the weight of a 10kg object that is moving at 5m/s

w = 98.1[N]

Explanation:

The weight of a body independent of its speed or acceleration, will always be equal to the product of its mass by the acceleration of gravity.

In this case we have:

w = m * g

where:

m = mass = 10 [kg]

g = gravity = 9.81[m/s^2]

w = 10 * 9.81 = 98.1 [N]

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
