A0.143 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/s. it has a head-on collision with a 0.298 kg glider that is moving to the left with a speed of 2.25 m/s. suppose the collision is elastic. find the magnitude of the final velocity of the 0.143kg glider. find the magnitude of the final velocity of the 0.298kg glider.

Explanation:

As we know that system of two gliders are moving on frictionless track

so momentum conservation is applied on it

So we will have

so we will have

now we know that collision is elastic so we have

so by solving above equations we have

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

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
