3. A 0.02 Kg marble moving to the right at 10 cm/s makes an head on collision with a 0.02 kg marble which is moving to the
left at 20 cm/s. After the collision the 1st marble moves to the left at 20 cm/s. Find the velocity of the 2nd marble after the
collision ?
M1V1i+ M2V2i = M1V1f + M2V2f
G 10 cm/s Right
10 cm/s Left

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.
