Suppose a 112 kg cart traveling 12 m/s hits and sticks to (non-moving) carr with mass of 98 kg. how fast in (m/s) will the two cars be going am instant after they hit?

a) 1.14 b) 6.4 c) 9.8 d) 5.11

state formula used to solve as well

answer:

explanation:

usually, u solve using ur mind, duhhh

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

neither accurate nor precise.
