When the wagon is at rest 50 meters up a 6.0 degree slope, an outlaw cuts it loose from the hoses with two boxes of gold weighing a combined 300 kg. The bandit intends to cause the wagon to crash into the canyon where his comrades are waiting after rolling down the slope and across the level terrain. But the Lone Ranger (mass 75.0kg) and Tonto are waiting in a tree 40 meters from the canyon's brink (mass60.0kg). They watch as it passes them below and then dive vertically into the wagon. Will they make it before the wagon overturns if it takes them 5.0 seconds to grab the gold and get out? b) Is the kinetic energy of the system comprising the two heroes plus the wagon preserved as they fall into the wagon? If not, does it change and if so, how much?
