Lengths and time intervals depend on the factor

according to the theory of relativity (Eqs. 26-1 and 26-3). Evaluate this factor for speeds of: (a) v= 20,000 m/s (typical speed of a satellite); (b) v = 0.020c; (c) v = 0.200c; (d) v = 0.95c; (e) v = 0.98c; (f) v = 0.999c.

NEWTON’S SECOND LAW ● an object’s change in motion (acceleration) is directly proportional to applied force ● an object’s change in motion (acceleration) is inversely proportional to the object’s mass ● mass is just a measure of inertia, an object’s stubbornness...
