A 32.0 kg cart is at rest on a frictionless, horizontal surface. The cart experiences an unbalanced force, causing the cart to accelerate at a rate of +5 m/s2

After traveling 200 meters, the cart no longer experiences an unbalanced force and did not interact with any other object. Select the response that correctly describes the motion of the cart after 200 meters.

A
The cart’s velocity will continue to increase at a rate of 5 m/s2.
B
The cart’s velocity will decrease because it is no longer accelerating.
C
The cart will return to a state of rest.
D
The cart will continue to travel at a constant velocity.

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.
