In this problem, we show that the clock's length appears shortened when viewed from a reference frame s in which the clock is moving with relative speed v to the right, parallel to its long axis. the key is to calculate explicitly the length of time that an observer in s will measure between "ticks" of the moving clock in terms of ls, the length of the clock in the s frame. comparing this with the known period of the clock in the s frame allows us to compute the length of the clock in the s frame. einstein used gedanken experiments such as this to clarify his thinking as he strove to remove inconsistencies from the basic formulations of physics. part a what is the period t0 between successive ticks of the clock in its rest frame? express your answer in terms of variables given in the introduction. use c for the speed of light.

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.
