Period: g = 10 m/s is a good approximation for the acceleration due to gravity on Earth, but for more accurate results use 9.81 m/s downwards, as specified in the reference tables. DIRECTIONS: 1) In each case, draw a vector diagram to imagine the problem. 2) Record all hidden and known values, 3) Find the equation that links those values to solve the problem. Show all work. CLASSWORK EXAMPLES 1a) A rock is dropped from a cliff. It takes exactly 4.50 seconds to hit the ground. How high is the cliff? Ignore air resistance. 1b) An athlete jumps to a peak height of 0.600 meters. What was her vertical jumping speed? Ignore air resistance 1c) A football is kicked verticaily with an initial speed of 22.0 m/s vertically from off the ground. How much time will it spend in the air before it hits the ground again? Ignore air resistance
