Block a, with a mass of 6.0 kg, is sliding across a frictionless track at 65 m/s when it collides with block b ( 9.0 kg) which is initially at rest . the two masses stick together and travel around a vertical loop with an unknown radius. they just barely make it around the vertical loop with an unknown radius.
a) calculate the centrifugal force acting on the masses at the top of the loop
b) calculate the velocity of the blocks just after the collision
c) calculate the radius of the loop so that the blocks just barely make it
d) calculate the normal force acting on the blocks when they reach the bottom after traveling through the loop

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.
