You are part of a searchand- rescue mission that has been called out to look for a lost explorer. You%u2019ve found the missing explorer, but you're separated from him by a 200--high cliff and a 30--wide raging river. To save his life, you need to get a 4.4 package of emergency supplies across the river. Unfortunately, you can't throw the package hard enough to make it across. Fortunately, you happen to have a 0.70 rocket intended for launching flares. Improvising quickly, you attach a sharpened stick to the front of the rocket, so that it will impale itself into the package of supplies, then fire the rocket at ground level toward the supplies.

 

Part A What minimum speed must the rocket have just before impact in order to save the explorer%u2019s life?
