A stationary 1000kg cannon fires a 50kg cannonball. The cannonball leaves the cannon at 150m/s and as a result, the cannon recoils at 7.5m/s in the opposite direction. What is the total momentum of the cannon and cannonball after firing?

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

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?

Ahot-air balloon is 11.0 m above the ground and rising at a speed of 7.00 m/s. a ball is thrown horizontally from the balloon basket at a speed of 9.00 m/s. ignore friction and air resistance and find the speed of the ball when it strikes the ground.
