... A 1200-kilogram car moving at 12 meters per second collides with a 2300-kilogram car that is waiting at rest at a traffic light. After the collision, the cars lock together and slide. Eventually, the combined cars are brought to rest by a force of kinetic friction as the rubber tires slide across t ...

... • Select an object(s) to which the equations of equilibrium are to be applied. • Draw a free-body diagram for each object chosen above. Include only forces acting on the object, not forces the object exerts on its environment. • Choose a set of x, y axes for each object and resolve all forces in ...

... • Action/reaction pairs are both “push” or both “pull”. You will never see a situation where action is “pull” but reaction is “push”. If several objects are treated together at the same time, then we analyze the objects as a system. We would consider a system in cases when several objects are connec ...
