The rest energy E of an object with rest mass m is given by Einstein's famous equation E = mc², where c is the speed of light in vacuum. Find E for an electron for which (to three significant figures) m = 9.11 × 10¯³' kg. The SI unit for E is the joule (J); 1J = 1 kg m²/s².

MODELING REAL LIFE The kinetic energy (in joules) of an object in motion is given by the formula KE = mv², where m is the mass (in kilograms) of the object and v is the velocity (in meters per second). Solve the formula for v. Then approximate the velocity of a 1200-kilogram car that has 360,000 joules of kinetic energy.
Kinetic energy KE (Chapter 5) has dimensions kgm2/s2. It can be written in terms of the momentum p (Chapter 6) and mass m as KE = p2/2m (a) Determine the proper units for momentum (p) using dimensional analysis. (b) Refer to Problem 2. Given the units of force, write a simple equation relating a constant force F exerted on an object, an interval of time t during which the force is applied, and the resulting momentum of the object, p.
