Practice problems
1. A cannon on a pirate ship was fired at an angle of 30 °, and the cannon ball came out of
the cannon at 40 m/s. Assuming we can neglect air resistance and that g=9.8m/s“,
calculate:
angle = 30
(Make table and write the given values)

Make table and write the given values

answer:

angle = 30

Explanation:

lol

he . if i may ask what i your question exactly?

explanation:

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
