Water flows uphill in narrowing pipe.  The pipe’s initial cross section area is .0024 m2, which narrows to 0.0012 m2.   The initial velocity of the water is 0.6m/s.  The change in height is 0.25 meters.image00160415f2760415f27.jpga. Use the equation of continuity to find the velocity of water at the top of the pipe. [BLANK-1] m/sb. What is the difference in pressure (P1 – P2) between the top and bottom of the pipe? [BLANK-2] Pa

Which of these is not measured in Joules?

The plot shows the position of a mass attached to a spring undergoing harmonic motion.  At the marked position, which statement best describes the velocity and acceleration? image01260415f27.gif 

A metal ball with a mass of 0.8 kg and a volume of 10-4 m3 is submerged in water with a density of 1000 kg/m3.  How much does it weigh while submerged?

How would you find the work in an adiabatic process?

An object accelerates from rest and accelerates at 4 m/s2.  How far does it travel in 3 seconds?

In a physics lab, a 0.5 kg cart moving 6 m/s collides with a 1 kg cart at rest.  If the carts stick together, how fast do they travel after the collision?

You let a cart roll down a ramp with an initial starting height of 1 m.  Assuming no friction, what is the velocity of the cart when it reaches the bottom?

A 2 kg block is pushed against a spring attached to a wall.  If the spring has a spring constant of 500 N/m and is compressed 5 cm, what is the speed of the block after leaving the spring?

Isaac Newton imagined shooting a cannonball fast enough that it would orbit the Earth. Assuming this is done near sea level where g = 9.8m/s2, what is the required speed of the cannonball?  Radius of Earth = 6.4E6 m and  assume no air resistance.  You can do this as a circular motion problem where the centripetal acceleration is the same as the acceleration due to gravity.
