The desperate contestants on a TV survival show are extremely hungry. The mere food they can notice is some fruit hanging on a branch high in a tree. Luckily, they encompass a spring they can employ to launch a rock. The spring constant is 1700 N/m, and they can compress the spring a maximum of 28 cm. All the rocks on the island seem to encompass a mass of 410 g.
Determine with what speed does the rock depart the spring?
When the fruit suspends 20 m above the ground, will they feast or go starving?
