1. A laboratory cart (ml 500 g) rests on a level track. It is connected to a lead weight (m2 100 g) suspended vertically off the end of a pulley as shown in the diagram below. The system is released, and the cart accelerates to the right. (Assume the string and pulley contribute negligible mass to the system and that friction is kept low enough that it can be ignored.)
