Question: 5 points a 381 mm diameter 00245 n table tennis...

Question details

(5 points) A 38.1 mm diameter, 0.0245 N table tennis ball is released from the bottom of a swimming pool. With what velocity does it rise to the surface? Assume it has reached its terminal velocity. (5 points) Estimate the velocity with which you would contact the ground if you jumped from an airplane at an altitude 5,000 ft and (a) air resistance is negligible, (b) air resistance is important, but one forgot your parachute (bummer) or (c) you use a 25-ft-diameter parachute. (5 points) 1-9 (5 points) Two velocity components of a steady, incompressible flow field are known: u 2ax + bxy + cy2 and u-axz-byz2, where a, b, and c are constants. Velocity component w is missing. Generate an expression for w as a function ofx, y, and z. 1. 2. 3. 4.
