Abullet with a mass of 0.005kg is moving at 500m/s and sticks into a block of wood with a mass of 5kg. what is the final velocity of the wood/bullet mass?

0.5 m/s

Explanation:

We can solve the problem by using the law of conservation of momentum, which states that the total momentum before the collision must be equal to the total momentum after the collision:

where:

is the mass of the bullet

is the initial velocity of the bullet

is the mass of the block

is the initial velocity of the block

is the final velocity of the bullet+block

Re-arrranging the equation and substituting numbers, we find:

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

i think the answer would be reserve.
