Module 41: Implications for Mass: Intuitive Explanation and Motivation - Problem 1

In this problem, you briefly compare relativistic mass and rest mass for objects in motion.

  1. 1. Question

    A 2000 kg car is racing along a highway. If its speed is 100 km/hr, which answer below most closely approximates the difference between its relativistic mass and its rest mass? (Approximate cc by 3×105km/sec.3 \times 10^5 \,\textrm{km/sec.})
