A spinter in 100 m race, covers 4m in first section 30m in next y sec 52 m in another 4 sec and finishes the race 10 sec. Then find : 1) Average velocity of a spinter
2)What is the peak velocity attend the
spinter
3)During which time interval is the e
laccelerating highest ?

the body's situation won't change the forces are equal opposit and on the same body

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
