My insight of the day. Quantum Mechanics makes Newton’s Law consistent in its two forms. Otherwise they would be inconsistent. So Newton knew some QMech. He knew 1. F=ma=mdv/dt and 2. F=dp/dt. These two are consistent in a framework where wave-particles…

The equation v = a*del_t is sometimes used to find velocity when acceleration and time are known. Another form of this equation is v = v_0 + a*del_t. In this second form of the equation, the function of the term v_0 is to: A. indicate that the equation is…

1. A ball is thrown with an initial velocity of 20 m/s at an angle of 30° above the horizontal. What is the instantaneous vertical velocity of the ball when it is 5.1 m above the release point? (g = 9.8 m/s^2) A. 0.2 m/s B. 6.6 m/s C. 10 m/s D. 17 m/s
