Question

5. Goliath moved forward at 3.0m/s. With what velocity does the earth move? Mass of Earth = 5.98x10^24kg. Assume mass of Goliath = 3500kg.

Answer 1

Answer #1

we can use the law of conservation of momentum to find out the velocity the earth should move

m₁v₁=m₂v₂

3x3500 = 5.98x10²⁴ x v₂

==> v₂=1.755x10^-21 m/s

Whic is negligible.
