The velocity of a particle moving along the x axis varies in time according to the expression v(t)= a+bt^2 where a=60 m/s, b=5.31 m/s^3, and t is in seconds. Discover the average acceleration in the time interval from t=0 to 3.37 seconds. Answer in units of m/s^2.
A woman is 1.7 m tall and has a mass of 51 kg. She moves past an observer with the direction of the motion parallel to her height. The observer measures her relativistic momentum to have a magnitude of 1.8 x 1012 kg·m/s. What does the observer measur..
