During a free fall swati was accelerating at -9.8m/s2. after 120 seconds how far did she travel? use the formula =1/2 * t^2 to solve your answer. (do not forget to keep units in your answer.)

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).
