Part 1: Assume that the North American continent can be represented by a slab of rock 4400 km on a side and 29 km deep and that the rock has an average mass density of 2900 kg/m³. The continent is moving at the rate of about 4.2 cm/year. What is the mass of the continent?
Answer in units of kg.

Part 2: What is the kinetic energy of the continent?
Answer in units of J.

Part 3: A jogger (of mass 73 kg) has the same kinetic energy as that of the continent. What would his speed be?
Answer in units of m/s.
