A 50.0 g golf ball is struck by a driver whose head has a mass of 500.0 kg. The final speed of the golf ball after leaving the tee is 45.0 m/s. Find the final momentum of the golf ball. A)2.5 kg·m/s
B)5.0 kg·m/s
C)7.5 kg·m/s
D)10.0 kg·m/s

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
