1. Read and Understand
What information are you given?
Mass= m = 0.15 kg
Speed of light = c = 300,000,000 m/s=3x108 m/s
2. Plan and Solve
What unknown are you trying to calculate?
The amount of energy produced = E = ?
What formula contains the given quantities and the unknown?
E = mc²
Replace each variable with its known variable and known value.
E = (0.15 kg)(3.00 × 108 m/s)²
E = 1.35 x 10¹6 kg.m²/s2 = 1.4 x 10¹6 J
3. Look Back and Check
Is your answer reasonable?
Yes, the calculated number is quite large compared to the mass, and the units
indicate energy.

- Problem 1. Mass-Energy conversion in the Sun (Palen, et. al. 3rd Edition, Chapter 11, problems 38, 39) The Sun produces energy by converting mass m into energy E according to E = mc2 where c is the speed of light (c = 300,000 km/sec). Show that if the Sun produces 3.85 × 1026 joules (J) of energy per second, it must convert 4.3 billion kg of mass per second into energy. Note that 1 J/s is a watt (W), which may be more familiar to you. How much mass has the Sun lost over its lifetime (4.5 billion years)? The current mass of the Sun is 2 × 1030.
