Question 1 0/5 pts A laboratory cart (m2 = 500 g) is pulled horizontally across a level track by a lead weight (m2 = 25 g) suspended vertically off the end of a pulley as shown in the diagram below. (Assume the string and pulley contribute negligible mass to the system and that friction is kept low enough to be ignored.) If the lead weight falls 85 cm, determine the final speed of the system (tip:...
