28.5 Exercise 6

Avg difficulty 2.5

(a) Find the momentum of a 1.00×109 kg1 . \text{00} \times \text{10}^{9} \text{ kg} asteroid heading towards the Earth at 30.0 km/s\text{30}.\text{0 km}/\text{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(\right. 1 / 2 \left.\right) v^{2} / c^{2} at low velocities.)
