The coordinates of a bird flying in the xy-plane are given by x(t) = αt and y(t) = 3.0 m - βt2, where α = 2.4 m/s and β = 1.2 m/s2. (a) sketch the path of the bird between t = 0 and t = 2.0 s. (b) calculate the velocity and acceleration vectors of the bird as functions of time. (c) calculate the magnitude and direction of the bird’s velocity and acceleration at t = 2.0 s. (d) sketch the velocity and acceleration vectors at t = 2.0 s. at this instant, is the bird’s speed increasing, decreasing, or not changing? is the bird turning? if so, in what direction?

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.
