Question

Solve for Their Momentum in SI Unit

1.) Pacific Plate moves 2in annually and has a mass on 4.34x10²² kg approximately

2.) The Rate of movement of North American Plate is 1cmper year and has a mass of 3.18x10²² kg approximately

3.) The Eurasian plate is moving about 3cmper year. It has a mass of 2.85x10²² kg approximately

Answer 1

1) The momentum is

$$p=mv=(4.34·10^{22})[0.0254·2/(365·24·3600)],\\ p=7·10^{13}\text{ kg}·\text{m/s}.$$

2) The momentum is

$$p=mv=(3.18·10^{22})[0.01/(365·24·3600)],\\ p=1·10^{13}\text{ kg}·\text{m/s}.$$

3) The momentum is

$$p=mv=(2.85·10^{22})[0.03/(365·24·3600)],\\ p=2.7·10^{13}\text{ kg}·\text{m/s}.$$
