In tennis a lob can be used to buy time to get into position. The approximate height s (feet) for a tennis ball that is hit at upward at v,ft/sec from a height of soft is modeled by s=-16t² + vt + So If the ball is hit at 55 feet per second from a height of 5.2 feet, approximately how long will the tennis ball be in the air before it strikes the ground? (Round your answer to 2 decimal places)
