What distance will a car cover accelerating from 12 m/s to 26 m/s in 14 sec?

=force × distance a. work b. velocity c. pressure d. momentum

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.

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value
