Robin throws a penny up in the air. If the penny's initial velocity is 1.0m/s[up] and it is launched from a height of 1.5 m, what is the maximum height of the penny above the ground?

1.55m

Explanation:

The formula for calculating the maximum height is expressed as;

H = u²/2g

u is the initial velocity

g is the acceleration due to gravity

Substitute

H = 1²/2(9.8)

H = 1/19.6

H = 0.051m

Since it is launched form a height of 1.5m, the height above the ground will be 1.5+0.051 = 1.55m

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
