Q1. The mass of the carbon atom is 2.0x10^-26.
(A) What is the kinetic energy of a carbon atom moving with the speed of 500 m/s?
(B) Two carbon atoms are joined by spring-like carbon-carbon bond. The potential energy stored in the bond has the value you calculated in part A if the bond is stretched 0.060 nm. What is the bond's spring constant?
Q2. A small boat is moving at a velocity of 3.35 m/s while it is accelerated by a river current perpendicular to the initial direction of motion. If current acceleration is 0.750 m/s^2, what will the new velocity of the boat be after 33.5 s?
