Recitation 8 2/9 Phys 218 Example 1 A rock is thrown from the bottom of a cliff with an initial velocity of 10 m/s at a 60° angle. Another rock is thrown with a velocity of 5 m/s horizontally from the top of the cliff with a height of 15.31 m. If both rocks are in the air for the same time, how far from the base of the cliff does each rock land? (a) x 1 = __________ (b) x 2 = __________ 8.84 m 8.84 m
