55PRACTICE PROBLEM
A circus acrobat performs a daring stunt by jumping off a high platform. Initially, the acrobat free-falls for 12.0 m. The acrobat reaches the safety net which provides a deceleration of -12.5 m/s2 and finally, he lands on the ground with a speed of 5.00 m/s. Determine the height of the platform from which the acrobat jumped. Neglect air resistance.
