1 Use the model s=- 788 +11+S, with g= 32 TVsec? or g = 9.8 m/sec? A As of 2011, the highest vertical leap on record is 60 in. For this record-setting jump, the person left the ground with an initial velocity of 8/5 flsec. (a) Write a model to express the record holder's height (in ft) above ground level / seconds after leaving the ground. (b) Use the model from part (a) to determine how long it would take the record holder to reach his maximum height of 60 in. (5 ft).
