This PhysCast uses momentum conservation to examine a collision in 2D.

This PhysCast explores how to solve a 2D motion problem where the initial velocity has both horizontal and vertical components.

The following PhysCast explores the use of Newtons 2nd and 3rd Law on for two connected objects.

This is a question that involves rotational motion. A uniform rod of mass M and length L is attached to a vertical wall by a frictionless hinge. The rod is held so that it is initially horizontal, and then released to fall. Determine the tangential acceleration of the end of the rod at the instant it is released.

In Figure (a), two identical retangular rods of metal are welded end to end, with T1 = 0 degrees C a left side and T2 = 1-- degrees C on the right side. In 2.0 min 10 J is conducted at a constant rate from the right to left side. How much time would it take ot conduct 10 J if the rods were welded side to side as in Figure (b).

We are going to look at a problem that is an example of a 2-d vector calculation. A cyclist travels along a horizontal road and 5.5 m/s. A strong wind blows from one side for 1 minute, after which the cyclist is moving at 7.0 m/s at an angle of 12 degrees to their intial direction. What was their average acceleration while the wind blew?

In this question we are asked what mass of steam at 100 degrees C must be mixed with 150 g of ice at its melting point in a thermally insulating container to produce water at 50 degrees C?

A 0.20 kg puck upon a frictionless ice surface is acted on by the forces shown in the diagrams. Find the resulting accelerations?
