Couette flow: flow between 2 long concentric cylinders of radii ro and ri, created by the rotation of one of them. solve the flow problem for a newtonian, incompressible fluid for the following two cases:

1. the outer cylinder of radius ro is rotating with an angular velocity ω (s^-1 for units). also calculate the torque for this.

2. the inner cylinder of radius ri is rotating with an angular velocity -ω (s^-1 for units). also calculate the torque for this.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Amodel rocket with a mass of 0.212 kg is launched into the air with an initial speed of 84 m/s. how much kinetic energy will the rocket have at a height of 214 m? assume there is no wind resistance. 634 j 303 j
