Two masses (ma= 3 kg, mg= 5 kg) are attached to a (massless) meter stick, at the 0 and 75 cm marks, respectively. a.) Where is the center of mass of this system? 46.87 cm, from mass A. b.) The system is then hung from a string, so that it stays horizontal. Where should the string be placed? cm, from mass A. c.) Now, if mass B was removed, how much force would need to be exerted at the 100 cm mark in order to keep the meter stick level*? size: X N, dir: downwards. d.) Now, if mass B was removed, and no additional force was supplied, calculate the size of the angular acceleration of the meter stick at that instant*. 20.90 rad/s? *For parts c-d, assume the string remains attached at the same location you found in part b.

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
