A circular disc of mass 20kg and radius 15cm is mounted in an horizontal cylindrical axle of radius 1.5cm. Calculate the K. E of the disc after 1.2sec if s force 12N is applied tangentially to the axle. Answer needed urgently pls, Thank you to anybody who can solve this my Ist semester exams is lest than 20 hours awayy​

explanation:

its math

probably not if net force is zero

it doesn't. it was imagined up in the middle ages.

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
