While standing on a frozen lake (µf = 0) you throw a rock with a mass of 2.25 kg at vb = 12.0 m/s. The distance between you and the rock when it lands is 15.2 m. If your mass is 32.5 kg and you take the initial height of the rock to be zero, at what angle did you throw the rock? Also, what is your velocity after throwing the rock?
