Find the power (in kw) needed to drive a centrifugal pump that discharges 0.1 m2/s of water with a tangential absolute velocity of 6.2 m/s, if the flow at the inlet is radial, and the rotor speeds at the rotor inlet and outlet are us 8 m/s and uz 17 m/s a. 4.96 *b. 10.54 c. 5.67 d. 12.47

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

Drag each item into the proper state of matter category.
