5.8 Exercise 6

Avg difficulty 2.5

(a) Find the momentum of a 1.00×109-kg1.00 \times 10^{9} -\text{kg} asteroid heading towards Earth at 30.0 km/s. (b) Find the ratio of this momentum to the classical momentum. (Hint: Use the approximation that γ=1+(1/2)v2/c2\gamma = 1 + \left(1 / 2\right) v^{2} / c^{2} at low velocities.)
