A 0.30-kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.20-kg puck that is initially moving along the x-axis with a velocity of 7.7 m/s. After the collision, the 0.20-kg puck has a speed of 4.6 m/s at an angle of

θ = 53°

to the positivex-axis.

(a) Determine the velocity of the 0.30-kg puck after the collision.

magnitude m/s

direction ° from the positive x-axis

(b) Find the fraction of kinetic energy lost in the collision.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
