A billiards ball B rests on a horizontal surface and is struck by another billiards ball A of the same mass m = 0.2 kg. Ball A is initially moving at 18 m/s and is deflected 28° from its original direction. Assume the collision is elastic.

A model rocket is fired vertically from the ground with a constant acceleration of 45.3 m/s2 for 1.46 s at which time its fuel is exhausted. What is the maximum height (in m) reached by the rocket?

A crude approximation for the x component of velocity in an incompressible laminar boundary layer is a linear variation from u = 0 at the surface (y = 0) to the freestream velocity, U, at the boundary-layer edge (y = δ).
