As the velocity of an inertial frame of reference increases with
respect to a stationary observer, Einstcin's theory of special
relativity predicts that the length of an object, measured in the
dimension parallel to the motion of the reference frame, will
A. decrease.
B. remain unchanged.
C. increase.
D. increase at first but start to decrease when the speed of the
reference frame equals half the speed of light.
E. decrease at first but start to increase when the speed of the
reference frame equals half the speed of light.
The rest energy E of an object with rest mass m is given by Albert 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 * 10-31 kg. The SI unit for E is the joule (J); 1 J = 1 kg . m2/s2.
-20. Two cyclists, Mike and Josh, simultaneously started toward each other
from two towns d = 24 km apart. Josh rode at vj = 25 km/h, and Mike

at UM = 15 km/h. The moment they start, a fly also starts from Josh
towards Mike and after reaching Mike, immediately returns towards
Josh. The fly continues back and forth motion between the cyclists till
the cyclists meet. Air speed of fly is UF = 30 km/h and the wind blows
always towards Mike with a constant velocity u = 10 km/h. Find the
total distance s flown by the fly.
