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.

Which segment has 0 heat flow and negative work?

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

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
