If the drag force on a sphere, fd, can be expressed as fd = f(d, v, rho, µ), in [mlt −2 ] (8) where d is the sphere diameter in units of [l], v is the free stream velocity in units of [lt −1 ], rho is the fluid density in units of [ml−3 ], and µ is the fluid viscosity in units of [ml−1t −1 ]. use the buckingham-pi theorem to determine a suitable set of dimensionless parameters.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
