Consider a compact car that is being driven at 111 km/h.
The acceleration of gravity is 9.8 m/s^2
From what height would the car have to be
dropped to have the same kinetic energy?
Answer in units of m.

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
