If a 1,000-kg car was moving at 35 m/s,what would be its kinetic energy expressed in the unusual (for kinetic energy)units of calories? (1 cal = 4.186 J)

Question

Quizplus · Accepted Answer

The kinetic energy (KE) is calculated using the formula KE = 0.5 * mass * velocity^2. For a 1,000-kg car moving at 35 m/s, KE = 0.5 * 1000 * 35^2 = 612,500 J. Converting joules to calories: 612,500 J / 4.186 J/cal = 146,303 cal, which is approximately 1.5 × 10^5 cal.
