Tiger woods hits 45.0-gram golf ball, giving it a speed of 75.0 m/sec. what momentum has tiger woods given to the golf ball

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

What pressure difference is required between the ends of a 2.0-m-long, 1.0-mm-diameter horizontal tube for 40 c water to flow through it at an average speed of 4.0 m/s?
