Speed of a rocket At t sec after liftof, the height of a rocket is 3t 2 ft. How fast is the rocket climbing 10 sec after liftof?

Physically the derivative of the position of an object is equivalent to the function that describes its velocity. Therefore we will derive the function and then evaluate it within 10 seconds.

Our function is initially given as

Evaluating at 10 seconds we have,

Therefore the rocket climb to 60m/s

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

find the sum of the two horizontal vectors and the sum of the two vertical vectors
