Mary wants to throw a can straight up into the air and then hit it with a second can. she wants the collision to occur at height h = 5.0 m above the throw point. in addition, she knows that she needs t1 = 4.0 s between successive throws. assume that she throws both cans with the same speed. take g to be 9.81 m/s2 .
(a) how long it takes (in seconds) after the first can has been thrown into the air for the two cans to collide? answer to 4 significant figures.
(b) find the initial speed of the cans (in meters/second) to 4 significant figures

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
